Trait TupleMap1 

pub trait TupleMap1<T, U> {
    type Output;

    // Required method
    fn map_1<Func>(self, f: Func) -> Self::Output
       where Func: FnOnce(T) -> U;
}

Allows to map the first element of a tuple to another type.

Required Methods

fn map_1<Func>(self, f: Func) -> Self::Output

where Func: FnOnce(T) -> U,

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.
