Trait Extend

pub trait Extend<B>: Functor<B> + Sized {
    // Required method
    fn extend<W>(self, f: W) -> <Self as HKT<B>>::Target
       where W: FnOnce(Self) -> B;
}

Required Methods

fn extend<W>(self, f: W) -> <Self as HKT<B>>::Target

where W: FnOnce(Self) -> B,

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.
