Trait ErrorDiagnostic 

pub trait ErrorDiagnostic: StdError + 'static {
    // Required method
    fn signature(&self) -> &'static str;

    // Provided methods
    fn tag(&self) -> Option<&Bytes> { ... }
    fn service(&self) -> Option<&'static str> { ... }
    fn backtrace(&self) -> Option<&Backtrace> { ... }
}

Provides diagnostic information for errors.

It enables classification, service attribution, and debugging context.

Required Methods

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

Returns a stable identifier for the specific error classification.

It is used for logging, metrics, and diagnostics.

Provided Methods

fn tag(&self) -> Option<&Bytes>

Returns an optional tag associated with this error.

The tag is user-defined and can be used for additional classification or correlation.

fn service(&self) -> Option<&'static str>

Returns the name of the responsible service, if applicable.

Used to identify upstream or internal service ownership for diagnostics.

fn backtrace(&self) -> Option<&Backtrace>

Returns a backtrace for debugging purposes, if available.

Dyn Compatibility

This trait is dyn compatible.

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