Available on crate feature layers-logging only.

LoggingInterceptor customizes log emission.

Required Methods

fn log( &self, info: &ServiceInfo, operation: Operation, context: &[(&str, &str)], message: &str, err: Option<&Error>, )

Called for every log event.

Inputs

• info: The service information used for this operation.
• operation: The operation being logged.
• context: Additional key-value context such as path, range, or counters.
• message: The event message, such as started, finished, or failed.
• err: The error associated with this event, if any.

Performance

This method runs inline with the operation path. Avoid expensive I/O, network calls, or long-running work here.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
