Trait ErrorMap

pub trait ErrorMap<T, E0> {
    type R;

    // Required method
    fn cxm<S, MF>(self, mf: MF) -> Self::R
       where MF: FnOnce() -> S,
             S: ToOwned<Owned = String>,
             String: Borrow<S>;
}

Required Associated Types

type R

Required Methods

fn cxm<S, MF>(self, mf: MF) -> Self::R

where MF: FnOnce() -> S, S: ToOwned<Owned = String>, String: Borrow<S>,

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.
