Struct MutGuard 

pub struct MutGuard<T> { /* private fields */ }

stores an inner element that must implement the Guard trait, and forbids mutable borrows except going through its guard() method.

Implementations

impl<T: Guard> MutGuard<T>

pub fn new(inner: T) -> MutGuard<T>

pub fn guard(&mut self) -> MutGuardBorrow<'_, T>

call this method to get mutable access to the underlying element

pub fn into_inner(self) -> T

returns the wrapped element, consuming the MutGuard

impl<'a, T> MutGuard<MutGuardWrapper<'a, T>>

pub fn wrap<F>(inner: T, f: F) -> MutGuard<MutGuardWrapper<'a, T>>

where F: 'a + for<'r> FnMut(&'r mut T),

This method automatically generates a Guard implementation that will call f after every time the inner element is mutably borrowed

Trait Implementations

impl<T> Deref for MutGuard<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.
