Trait Implementations

impl ErrorMessageTracer for AnyhowTracer

fn new_message<E: Display>(err: &E) -> Self

Creates a new error trace, starting from a source error detail that implements Display.

fn add_message<E: Display>(self, err: &E) -> Self

Adds new error detail to an existing trace.

fn as_error(&self) -> Option<&(dyn Error + 'static)>

If the std feature is enabled, the error tracer also provides method to optionally converts itself to a dyn Error.

impl<E> ErrorTracer<E> for AnyhowTracer where
    E: Error + Send + Sync + 'static, 

fn new_trace(err: E) -> Self

Create a new error trace from E, also taking ownership of it.

fn add_trace(self, err: E) -> Self

Add a new error trace from E. In the current underlying implementation, this is effectively still has the same behavior as ErrorMessageTracer::add_message. This is because eyre and anyhow do not support adding new set of backtraces to an existing trace. So effectively, currently the error tracers can track at most one backtrace coming from the original error source.
