Trait Tuple3Map0Option 

pub trait Tuple3Map0Option<T0, T1, T2> {
    // Required method
    fn map0<U>(self, f: impl FnOnce(T0) -> U) -> Option<(U, T1, T2)>;
}

Required Methods

fn map0<U>(self, f: impl FnOnce(T0) -> U) -> Option<(U, T1, 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.
