Required Methods

fn transpose_map_err<Eo>( self, f0: impl FnOnce(E0) -> Eo, f1: impl FnOnce(E1) -> Eo, f2: impl FnOnce(E2) -> Eo, f3: impl FnOnce(E3) -> Eo, ) -> Self::OutTuple<Eo>

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.
