Trait ControlEventLedger 

Source 
pub trait ControlEventLedger: Send + Sync {
    // Required method
    fn emit(
        &self,
        ctx: &ControlEventCtx<'_>,
        event: ControlEvent,
    ) -> Result<EventId, ControlEventError>;
}
Expand description

Persistence sink for control events.

emit is synchronous. Callers running under ControlEventConfig::compliance_mode MUST treat Err as “abort the originating mutation” (fail closed). Callers in the default mode may log-and-continue, but the trait never swallows the failure on their behalf — that policy is per-caller.

Required Methods§

Source

fn emit( &self, ctx: &ControlEventCtx<'_>, event: ControlEvent, ) -> Result<EventId, ControlEventError>

Dyn Compatibility§

This trait is dyn compatible.

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