Trait Tuple3Map1Option 

pub trait Tuple3Map1Option<T0, T1, T2> {
    // Required method
    fn map1<U>(self, f: impl FnOnce(T1) -> U) -> Option<(T0, U, T2)>;
}

Mapping .1 for Tuple3

Required Methods

fn map1<U>(self, f: impl FnOnce(T1) -> U) -> Option<(T0, U, T2)>

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.
