Trait TransactionObserver 

pub trait TransactionObserver:

    // Required methods
    fn name(&self) -> &'static str;
    fn requirements(&self) -> ObserverRequirements;
    fn on_commit(&self, event: &TransactionEvent<'_>) -> Result<()>;
}

Trait implemented by every consumer of the post-commit observation surface (audit, replication, etc.).

See module docs for the full contract.

Required Methods

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

A short identifier for diagnostics and observability — appears in error logs and metric labels. Conventionally crate-shortname like "audit" or "replication".

fn requirements(&self) -> ObserverRequirements

Declare which optional TransactionEvent fields this observer needs the backend to populate. Called once at registration time; cached by the backend.

fn on_commit(&self, event: &TransactionEvent<'_>) -> Result<()>

Called inside the backend’s commit path, after the storage write succeeded. See module docs for failure semantics.

Errors

Returns the observer-specific YetiError when post-commit processing fails. The backend logs the error and continues — observer failures do not roll back the write.

Dyn Compatibility

This trait is dyn compatible.

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