Available on crate feature virtual-clients-draft and (32-bit or 64-bit) only.

Error joining a higher-level group as a virtual client’s sibling emulator by processing another sibling’s external commit (MlsGroup::vc_join_via_sibling_external_commit).

Variants

LibraryError(LibraryError)

See LibraryError for more details.

MissingRatchetTree

No ratchet tree available to build the prior-epoch public group.

PublicGroupError(CreationFromExternalError<StorageError>)

The prior-epoch public tree is invalid. See CreationFromExternalError.

ProcessMessageError(ProcessMessageError<StorageError>)

The external commit could not be parsed or verified.

StageCommitError(StageCommitError)

Staging the external commit failed.

MergeCommitError(MergeCommitError<StorageError>)

Merging the external commit failed.

NotAnExternalCommit

The message is not an external commit (Sender::NewMemberCommit with a Commit body).

MissingDerivationInfo

The external commit’s leaf carries no virtual-clients derivation info, so a sibling cannot reconstruct the joining state from it.

EpochIdMismatch

The derivation info references a different emulation epoch than the one supplied.

VirtualClientsError(VirtualClientsError)

A virtual-clients processing error occurred.

StorageError(StorageError)

An error occurred when writing the group to storage.
