Trait ChainErr

pub trait ChainErr<T> {
    // Required method
    fn chain_err<C>(self, context: C) -> Result<T, StrError>
       where C: IntoChained;
}

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.
