Struct PostgresCheckpointSink 

pub struct PostgresCheckpointSink { /* private fields */ }

Postgres append-only checkpoint sink. Anchors signed checkpoints to a separate database so a host attacker cannot silently rewrite or truncate the local chain without being detected on the next verify.

Implementations

impl PostgresCheckpointSink

pub async fn connect(url: &str) -> Result<Self, CheckpointSinkError>

Connect to url, create the append-only audit_checkpoints table if it does not exist, and return the sink.

Trait Implementations

impl CheckpointSink for PostgresCheckpointSink

fn append<'life0, 'life1, 'async_trait>( &'life0 self, checkpoint: &'life1 Checkpoint, ) -> Pin<Box<dyn Future<Output = Result<(), CheckpointSinkError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Append one signed checkpoint. Must not overwrite prior checkpoints.

fn load_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Checkpoint>, CheckpointSinkError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Load every stored checkpoint, ordered by seq ascending.

impl Debug for PostgresCheckpointSink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
