Trait ErrorChainExt

pub trait ErrorChainExt {
    // Required methods
    fn chain(&self) -> DisplayErrorChain<&Self>;
    fn into_chain(self) -> DisplayErrorChain<Self>
       where Self: Sized;
}

An extension trait for Error types to display their sources in a chain.

Required Methods

fn chain(&self) -> DisplayErrorChain<&Self>

Provides an fmt::Display implementation for an error as a chain.

fn into_chain(self) -> DisplayErrorChain<Self>

where Self: Sized,

Same as chain, but consumes self.

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.
