Blanket Implementations

impl<I> IntoIterator for Keys<'a, K, V> where I: Iterator,

type Item = <I as Iterator>::Item;
type IntoIter = I;
fn into_iter(self) -> I

impl<T> Any for Keys<'a, K, V> where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

impl<T> Borrow<T> for Keys<'a, K, V> where T: ?Sized,

fn borrow(&self) -> &T

impl<T> BorrowMut<T> for Keys<'a, K, V> where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

impl<T> From<T> for Keys<'a, K, V>

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for Keys<'a, K, V> where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of [From]<T> for U chooses to do.

type Error = never;

impl<T, U> TryInto<U> for Keys<'a, K, V> where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error;
fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>
