Trait Implementations

impl<'a, T, E, U: Validator<Item = T, Error = E>> AsMut<T> for Guard<'a, T, E, U>

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

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'a, T, E, U: Validator<Item = T, Error = E>> AsRef<T> for Guard<'a, T, E, U>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, T: Debug + 'static, E: Debug, U: Debug + Validator<Item = T, Error = E>> Debug for Guard<'a, T, E, U>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T, E, U: Validator<Item = T, Error = E>> Deref for Guard<'a, T, E, U>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, T, E, U: Validator<Item = T, Error = E>> DerefMut for Guard<'a, T, E, U>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
