Struct Lens 

pub struct Lens<PO: Strong<S, T>, PI: Strong<A, B>, S, T, A, B>(pub Optic<PO, PI, S, T, A, B>);

A Lens is a type of Optic that focuses on a part A of a whole S, allowing both getting the part and setting it (which might change S to T and A to B).

Lenses are typically built from Strong profunctors. This Lens struct wraps an Optic.

Tuple Fields

0: Optic<PO, PI, S, T, A, B>

The underlying Optic representation of the lens.

Trait Implementations

impl<PO: Strong<S, T>, PI: Strong<A, B>, S, T, A, B> Deref for Lens<PO, PI, S, T, A, B>

type Target = Optic<PO, PI, S, T, A, B>

The resulting type after dereferencing.

fn deref(&self) -> &Optic<PO, PI, S, T, A, B>

Dereferences the value.

impl<PA: Strong<S, T>, PB: Strong<A, B>, S: 'static, T: 'static, A: 'static, B: 'static> From<Lens<PA, PB, S, T, A, B>> for Optic<PA, PB, S, T, A, B>

fn from(value: Lens<PA, PB, S, T, A, B>) -> Self

Converts to this type from the input type.
