Required Methods§
fn broadcasts(
&self,
match_all_topics: &[[u8; 32]]
) -> Result<Vec<Vec<u8, Global>, Global>, Error>
fn broadcasts( &self, match_all_topics: &[[u8; 32]] ) -> Result<Vec<Vec<u8, Global>, Global>, Error>
Return the data of all known statements which include all topics and have no DecryptionKey
field.
fn posted(
&self,
match_all_topics: &[[u8; 32]],
dest: [u8; 32]
) -> Result<Vec<Vec<u8, Global>, Global>, Error>
fn posted( &self, match_all_topics: &[[u8; 32]], dest: [u8; 32] ) -> Result<Vec<Vec<u8, Global>, Global>, 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).
fn posted_clear(
&self,
match_all_topics: &[[u8; 32]],
dest: [u8; 32]
) -> Result<Vec<Vec<u8, Global>, Global>, Error>
fn posted_clear( &self, match_all_topics: &[[u8; 32]], dest: [u8; 32] ) -> Result<Vec<Vec<u8, Global>, Global>, Error>
Return the decrypted data of all known statements whose decryption key is identified as
dest
. The key must be available to the client.
fn submit(&self, statement: Statement, source: StatementSource) -> SubmitResult
fn submit(&self, statement: Statement, source: StatementSource) -> SubmitResult
Submit a statement.
