Expand description

Interface defining the identity store, which may be in-memory, on-disk, etc.

Signal clients usually use the identity store in a TOFU manner, but this is not required.

Required Methods§

Source

fn get_identity_key_pair<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<IdentityKeyPair, SignalProtocolError>> + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Return the single specific identity the store is assumed to represent, with private key.

Source

fn get_local_registration_id<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u32, SignalProtocolError>> + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Return a u32 specific to this store instance.

This local registration id is separate from the per-device identifier used in [ProtocolAddress] and should not change run over run.

If the same device is unregistered, then registers again, the [ProtocolAddress::device_id] may be the same, but the store registration id returned by this method should be regenerated.

Source

fn save_identity<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, address: &'life1 ProtocolAddress, identity: &'life2 IdentityKey, ) -> Pin<Box<dyn Future<Output = Result<IdentityChange, SignalProtocolError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Record an identity into the store. The identity is then considered “trusted”.

The return value represents whether an existing identity was replaced.

Source

fn is_trusted_identity<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, address: &'life1 ProtocolAddress, identity: &'life2 IdentityKey, direction: Direction, ) -> Pin<Box<dyn Future<Output = Result<bool, SignalProtocolError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Return whether an identity is trusted for the role specified by direction.

Source

fn get_identity<'life0, 'life1, 'async_trait>( &'life0 self, address: &'life1 ProtocolAddress, ) -> Pin<Box<dyn Future<Output = Result<Option<IdentityKey>, SignalProtocolError>> + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Return the public identity for the given address, if known.
