Trait Pipe0Ref 

pub trait Pipe0Ref {
    // Provided methods
    fn pipe0_with<'a, X: ?Sized + 'a, R: 'a>(
        &'a self,
        proj: impl FnOnce(&'a Self) -> &'a X,
        f: impl FnOnce(&'a X) -> R,
    ) -> impl FnOnce() -> R { ... }
    fn pipe0_with_mut<'a, X: ?Sized + 'a, R: 'a>(
        &'a mut self,
        proj: impl FnOnce(&'a mut Self) -> &'a mut X,
        f: impl FnOnce(&'a mut X) -> R,
    ) -> impl FnOnce() -> R { ... }
}

Borrow-based arity-0 piping.

Fixes the first argument to self (possibly projected) and returns a nullary closure.

Provided Methods

fn pipe0_with<'a, X: ?Sized + 'a, R: 'a>( &'a self, proj: impl FnOnce(&'a Self) -> &'a X, f: impl FnOnce(&'a X) -> R, ) -> impl FnOnce() -> R

Partially applies f by fixing its first argument to proj(&self), returning a nullary closure.

Law: self.pipe0_with(proj, f)() = f(proj(&self)).

fn pipe0_with_mut<'a, X: ?Sized + 'a, R: 'a>( &'a mut self, proj: impl FnOnce(&'a mut Self) -> &'a mut X, f: impl FnOnce(&'a mut X) -> R, ) -> impl FnOnce() -> R

Partially applies f by fixing its first argument to proj(&mut self), returning a nullary closure.

Law: self.pipe0_with_mut(proj, f)() = f(proj(&mut self)).

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.
