Trait BoxedErrorExt

pub trait BoxedErrorExt<E: ?Sized>: BoxedSealed + Sized {
    // Required methods
    fn context<M: Display>(self, msg: M) -> BoxContext<M, E>;
    fn chain(&self) -> Chain<'_> ;

    // Provided methods
    fn find_source<T: Error + 'static>(&self) -> Option<&T> { ... }
    fn display<S: Display>(&self, separator: S) -> DisplayChain<'_, S> { ... }
}

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<'_>

Equivalent of ErrorExt::chain.

Provided Methods

fn find_source<T: Error + 'static>(&self) -> Option<&T>

Equivalent of ErrorExt::find_source.

fn display<S: Display>(&self, separator: S) -> DisplayChain<'_, S>

Equivalent of ErrorExt::display.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
