Trait TransactionObserver 

Source
pub trait TransactionObserver: Send + Sync {
    // Required methods
    fn name(&self) -> &'static str;
    fn apply<'life0, 'life1, 'async_trait>(
        &'life0 self,
        tx_result: &'life1 TransactionResult,
    ) -> Pin<Box<dyn Future<Output = Result<(), ClientError>> + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}
Expand description

Side-effect-only observer of committed transactions. apply() runs once per apply_transaction AFTER the standard updates land. Errors are logged (tagged with Self::name) and never abort sync.

Required Methods§

Source

fn name(&self) -> &'static str

Short identifier for tracing::warn! events on apply() errors.

Source

fn apply<'life0, 'life1, 'async_trait>( &'life0 self, tx_result: &'life1 TransactionResult, ) -> Pin<Box<dyn Future<Output = Result<(), ClientError>> + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Return Ok(()) for “not interested”; reserve Err(_) for genuine internal failures.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
