impl ProcessedWelcome

pub fn new_from_welcome<Provider: OpenMlsProvider>( provider: &Provider, mls_group_config: &MlsGroupJoinConfig, welcome: Welcome, ) -> Result<Self, WelcomeError<Provider::StorageError>>

Creates a new processed Welcome message , which can be inspected before creating a StagedWelcome.

This does not require a ratchet tree yet.

NOTE: The group info contains unverified values. Use with caution.

pub fn psks(&self) -> &[PreSharedKeyId]

Get a reference to the PSKs in this Welcome message.

NOTE: The group info contains unverified values. Use with caution.

pub fn into_staged_welcome<Provider: OpenMlsProvider>( self, provider: &Provider, ratchet_tree: Option<RatchetTreeIn>, ) -> Result<StagedWelcome, WelcomeError<Provider::StorageError>>

Consume the ProcessedWelcome and combine it with the ratchet tree into a StagedWelcome.

pub fn export_secret<CryptoProvider: OpenMlsCrypto>( &self, crypto: &CryptoProvider, label: &str, context: &[u8], key_length: usize, ) -> Result<Vec<u8>, ExportSecretError>

Exports a secret from the epoch of the group that is joined using this ProcessedWelcome. Returns ExportSecretError::KeyLengthTooLong if the requested key length is too long.

pub fn own_key_package(&self) -> Option<&KeyPackage>

Retrieve a reference to the own KeyPackage that was retrieved from local storage as part of Welcome processing, and is used to build the group
