Struct failure::Compat

source · [−]

pub struct Compat<E> { /* private fields */ }

Expand description

A compatibility wrapper around an error type from this crate.

Compat implements std::error::Error, allowing the types from this crate to be passed to interfaces that expect a type of that trait.
