Struct UsizeKeyPath

pub struct UsizeKeyPath<const N: usize>;

The same as KeyPath, but for index-based keypaths as opposed to field-based.

Trait Implementations

impl<const N: usize> Clone for UsizeKeyPath<N>

fn clone(&self) -> UsizeKeyPath<N>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const N: usize> Default for UsizeKeyPath<N>

fn default() -> UsizeKeyPath<N>

Returns the “default value” for a type.

impl<'t, const N: usize, T> KeyPathIndexable<UsizeKeyPath<N>> for &'t T

where T: Index<usize>,

type Output = &'t <T as Index<usize>>::Output

fn idx(self) -> Self::Output

impl<'t, const N: usize, T> KeyPathIndexable<UsizeKeyPath<N>> for &'t mut T

where T: IndexMut<usize>,

type Output = &'t mut <T as Index<usize>>::Output

fn idx(self) -> Self::Output

impl<const N: usize, T> KeyPathIndexable<UsizeKeyPath<N>> for Vec<T>

A special-cased implementation for move-by-indexing with a Vec, as there is no standard trait to implement such a thing (since Index and IndexMut only allow ref-by-index and mut-ref-by-index, respectively.

type Output = T

fn idx(self) -> Self::Output

impl<const N: usize> Copy for UsizeKeyPath<N>
