Statement store API.

Required Methods§

Source

fn statements(&self) -> Result<Vec<([u8; 32], Statement)>, Error>

Return all statements.

Source

fn statement(&self, hash: &[u8; 32]) -> Result<Option<Statement>, Error>

Get statement by hash.

Source

fn broadcasts( &self, match_all_topics: &[[u8; 32]], ) -> Result<Vec<Vec<u8>>, Error>

Return the data of all known statements which include all topics and have no DecryptionKey field.

Source

fn posted( &self, match_all_topics: &[[u8; 32]], dest: [u8; 32], ) -> Result<Vec<Vec<u8>>, Error>

Return the data of all known statements whose decryption key is identified as dest (this will generally be the public key or a hash thereof for symmetric ciphers, or a hash of the private key for symmetric ciphers).

Source

fn posted_clear( &self, match_all_topics: &[[u8; 32]], dest: [u8; 32], ) -> Result<Vec<Vec<u8>>, Error>

Return the decrypted data of all known statements whose decryption key is identified as dest. The key must be available to the client.

Source

fn submit(&self, statement: Statement, source: StatementSource) -> SubmitResult

Submit a statement.

Source

fn remove(&self, hash: &[u8; 32]) -> Result<(), Error>

Remove a statement from the store.
