An extension trait for Errors.

Required Methods

fn with_source<Source>(self, source: Source) -> ErrorWithSource<Self, Source>

where Self: Sized,

fn caused<Error>(self, error: Error) -> ErrorWithSource<Error, Self>

where Self: Sized,

Set self as the source of the given error.

The value of self will be returned by the Error::source and Error::cause implementations of the returned value. Note that the latter is deprecated.

fn display_with_sources<I>(&self, infix: I) -> DisplayWithSources<&Self, I>
