An equivalent of ErrorExt for boxed errors.

This is effectively the same trait as ErrorExt, but for boxed errors. It exists separately purely for implementation reasons.

Required methods

fn context<M: Display>(self, msg: M) -> BoxContext<M, E>

Equivalent of ErrorExt::context.

fn chain(&self) -> Chain<'_>ⓘ

Notable traits for Chain<'a>

impl<'a> Iterator for Chain<'a> type Item = &'a (dyn Error + 'static);

Equivalent of ErrorExt::chain.
