Trait Tuple4Map3Result 

pub trait Tuple4Map3Result<E, T0, T1, T2, T3> {
    // Required method
    fn map3<U>(self, f: impl FnOnce(T3) -> U) -> Result<(T0, T1, T2, U), E>;
}

Mapping .3 for Tuple4

Required Methods

fn map3<U>(self, f: impl FnOnce(T3) -> U) -> Result<(T0, T1, T2, U), E>

Mapping .3 for Tuple4

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.
