Expand description

StorageProvider describes the storage backing OpenMLS and persists the state of OpenMLS groups.

The getters for individual values usually return a Result<Option<T>, E>, where Err(_) indicates that some sort of IO or internal error occurred, and Ok(None) indicates that no error occurred, but no value exists. Many getters for lists return a Result<Vec<T>, E>. In this case, if there was no error but the value doesn’t exist, an empty vector should be returned.

Any value that uses the group id as key is required by the group. Returning None or an error for any of them will cause a failure when loading a group.

More details can be taken from the comments on the respective method.

Required Associated Types§

type Error: Debug + Error

An opaque error returned by all methods on this trait.

Required Methods§

fn write_mls_join_config<GroupId, MlsGroupJoinConfig>( &self, group_id: &GroupId, config: &MlsGroupJoinConfig, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, MlsGroupJoinConfig: MlsGroupJoinConfig<VERSION>,

Writes the MlsGroupJoinConfig for the group with given id to storage

fn append_own_leaf_node<GroupId, LeafNode>( &self, group_id: &GroupId, leaf_node: &LeafNode, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, LeafNode: LeafNode<VERSION>,

Adds an own leaf node for the group with given id to storage

fn queue_proposal<GroupId, ProposalRef, QueuedProposal>( &self, group_id: &GroupId, proposal_ref: &ProposalRef, proposal: &QueuedProposal, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, ProposalRef: ProposalRef<VERSION>, QueuedProposal: QueuedProposal<VERSION>,

Enqueue a proposal.

A good way to implement this could be to add a proposal to a proposal store, indexed by the proposal reference, and adding the reference to a per-group proposal queue list.

fn write_tree<GroupId, TreeSync>( &self, group_id: &GroupId, tree: &TreeSync, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, TreeSync: TreeSync<VERSION>,

Write the TreeSync tree.

fn write_interim_transcript_hash<GroupId, InterimTranscriptHash>( &self, group_id: &GroupId, interim_transcript_hash: &InterimTranscriptHash, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, InterimTranscriptHash: InterimTranscriptHash<VERSION>,

Write the interim transcript hash.

fn write_context<GroupId, GroupContext>( &self, group_id: &GroupId, group_context: &GroupContext, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, GroupContext: GroupContext<VERSION>,

Write the group context.

fn write_confirmation_tag<GroupId, ConfirmationTag>( &self, group_id: &GroupId, confirmation_tag: &ConfirmationTag, ) -> Result<(), Self::Error>

where GroupId: GroupId<VERSION>, ResumptionPskStore: ResumptionPskStore<VERSION>,

Writes the ResumptionPskStore for the group with the given id.

fn write_own_leaf_index<GroupId, LeafNodeIndex>( &self, group_id: &GroupId, own_leaf_index: &LeafNodeIndex, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, LeafNodeIndex: LeafNodeIndex<VERSION>,

Writes the own leaf index inside the group for the group with the given id.

fn write_group_epoch_secrets<GroupId, GroupEpochSecrets>( &self, group_id: &GroupId, group_epoch_secrets: &GroupEpochSecrets, ) -> Result<(), Self::Error>

fn write_vc_emulation_epoch_state<EpochId, VcEmulationEpochState>( &self, epoch_id: &EpochId, vc_emulation_epoch_state: &VcEmulationEpochState, ) -> Result<(), Self::Error>
where EpochId: VcEpochId<VERSION>, VcEmulationEpochState: VcEmulationEpochState<VERSION>,

Available on crate feature virtual-clients-draft only.

Write the virtual clients per-emulation-epoch state (the AEAD key plus the registering client’s emulation-group leaf index) for the given epoch.

fn write_vc_emulation_bindings<GroupId, VcEmulationBindings>( &self, group_id: &GroupId, bindings: &VcEmulationBindings, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>, VcEmulationBindings: VcEmulationBindings<VERSION>,

Available on crate feature virtual-clients-draft only.

Store the record binding each recent epoch of a higher-level group to the emulation-group epoch whose virtual-client LeafNode was active at that epoch. Used by the reuse-guard derivation path to look up the per-message ReuseGuardSecret for the epoch a message was sent in.

The record is updated on every commit merged on the higher-level group and prunes its own entries in lockstep with the group’s message-secrets retention. A subsequent write replaces any previously stored record.

fn write_vc_operation_tree<EpochId, VcOperationTree>( &self, epoch_id: &EpochId, vc_operation_tree: &VcOperationTree, ) -> Result<(), Self::Error>
where EpochId: VcEpochId<VERSION>, VcOperationTree: VcOperationTree<VERSION>,

Available on crate feature virtual-clients-draft only.

Write the per-emulation-epoch Virtual Client Operation Secret Tree (the lazily derived node secrets plus the per-leaf operation ratchets) for the given epoch. The tree is written back after every ratchet advance. It is stored separately from the static EmulationEpochState so that per-operation writes do not rewrite the static fields.

fn write_retained_key_package_material_batch<EpochId, VcOperationTree, KeyPackageRef, RetainedKeyPackageMaterial>( &self, epoch_id: &EpochId, operation_tree: &VcOperationTree, materials: &[(KeyPackageRef, RetainedKeyPackageMaterial)], ) -> Result<(), Self::Error>
where EpochId: VcEpochId<VERSION>, VcOperationTree: VcOperationTree<VERSION>, KeyPackageRef: HashReference<VERSION>, RetainedKeyPackageMaterial: RetainedKeyPackageMaterial<VERSION>,

Available on crate feature virtual-clients-draft only.

Store the advanced operation secret tree for epoch_id together with the retained virtual clients KeyPackage material for every reference in materials.

A sibling calls this once when it processes a KeyPackageUpload: the upload consumes one operation generation in the tree and produces one RetainedKeyPackageMaterial per KeyPackage. These writes belong together: the tree must never be persisted as advanced without the materials it produced. Providers do not open their own transaction, so an application using a transactional provider (such as SQLite) should call this within a transaction to get atomicity and rollback on error. The in-memory provider applies the writes while holding its write lock. Each material is keyed by its HashReference and tagged with epoch_id so the epoch-liveness query (Self::has_retained_key_package_material_for_epoch) can find it. A subsequent write for the same reference replaces the stored material.

fn write_signature_key_pair<SignaturePublicKey, SignatureKeyPair>( &self, public_key: &SignaturePublicKey, signature_key_pair: &SignatureKeyPair, ) -> Result<(), Self::Error>
where SignaturePublicKey: SignaturePublicKey<VERSION>, SignatureKeyPair: SignatureKeyPair<VERSION>,

where HashReference: HashReference<VERSION>, KeyPackage: KeyPackage<VERSION>,

Store key packages.

Store a key package. This includes the private init key. The encryption key is stored separately with write_encryption_key_pair.

Note that it is recommended to store a list of the hash references as well in order to iterate over key packages. OpenMLS does not have a reference for them.

fn write_psk<PskId, PskBundle>( &self, psk_id: &PskId, psk: &PskBundle, ) -> Result<(), Self::Error>
where PskId: PskId<VERSION>, PskBundle: PskBundle<VERSION>,

Delete a key package based on the hash reference.

Under the virtual-clients-draft feature, an implementation must also delete the retained virtual clients KeyPackage material stored for the same reference (see Self::delete_retained_key_package_material). Deleting non-existent material is a no-op, so this is safe for KeyPackages that were never uploaded by a virtual client.

where EpochId: VcEpochId<VERSION>,

Available on crate feature virtual-clients-draft only.

Delete all per-epoch state for the given emulation epoch (both the emulation epoch state and the Virtual Client Operation Secret Tree), but only if no retained virtual clients KeyPackage material still references it.

Returns Ok(true) if the epoch state was deleted, and Ok(false) if it was kept because retained material still references the epoch. The liveness check and the deletion belong together. Providers do not open their own transaction, so an application using a transactional provider (such as SQLite) should call this within a transaction, so a material stored concurrently cannot be orphaned by a deletion that already observed the epoch as unreferenced. The in-memory provider holds its write lock across both.

fn delete_vc_emulation_bindings<GroupId>( &self, group_id: &GroupId, ) -> Result<(), Self::Error>
where GroupId: GroupId<VERSION>,

Available on crate feature virtual-clients-draft only.

Remove the per-epoch emulation bindings of the given group. Called when the group is being deleted.

where KeyPackageRef: HashReference<VERSION>,

Available on crate feature virtual-clients-draft only.

Delete the retained virtual clients KeyPackage material stored for the given KeyPackage reference. Called from Self::delete_key_package so the material is removed together with the KeyPackage it describes.
