Trait implemented by errors produced by this crate.

It extends std::error::Error semantics with optional error metadata, and a source method where sources may also provide metadata.

Required Methods

fn as_std(&self) -> &(dyn Error + Send + Sync + 'static)

Returns this error as a std error reference.

fn into_std(self: Box<Self>) -> Box<dyn Error + Send + Sync>

Returns this error as a std error.

fn as_dyn(&self) -> &dyn StackError

Returns this error as a dyn StackError.

fn meta(&self) -> Option<&Meta>

Returns metadata captured at creation time, if available.

fn source(&self) -> Option<ErrorRef<'_>>

Returns the next source in the chain, if any.

fn fmt_message(&self, f: &mut Formatter<'_>) -> Result

Returns the next source in the chain, if any.

fn is_transparent(&self) -> bool

Returns whether this error is transparent and should be skipped in reports.

Provided Methods

fn as_ref(&self) -> ErrorRef<'_>

Returns this error as an ErrorRef.

See ErrorRef for details.

fn stack(&self) -> Chain<'_>

Returns an iterator over this error followed by its sources.

fn sources(&self) -> Chain<'_>

Returns an iterator over sources of this error (skipping self).

fn report(&self) -> Report<'_>

Returns a Report to output the error with configurable formatting.

Dyn Compatibility

This trait is dyn compatible.

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