Struct script::dom::bindings::import::module::CustomAutoRooterGuard

pub struct CustomAutoRooterGuard<'a, T>where
    T: 'a + CustomTrace,{
    rooter: &'a mut CustomAutoRooter<T>,
}

An RAII guard used to root underlying data in CustomAutoRooter until the guard is dropped (falls out of scope). The underlying data can be accessed through this guard via its Deref and DerefMut implementations. This structure is created by root method on CustomAutoRooter or by the auto_root! macro.

Fields

rooter: &'a mut CustomAutoRooter<T>

Implementations

impl<'a, T> CustomAutoRooterGuard<'a, T>where T: 'a + CustomTrace,

pub fn new( cx: *mut JSContext, rooter: &'a mut CustomAutoRooter<T> ) -> CustomAutoRooterGuard<'a, T>

pub fn handle(&'a self) -> Handle<'a, T>where T: RootKind,

pub fn handle_mut(&mut self) -> MutableHandle<'_, T>where T: RootKind,

Trait Implementations

impl<'a, T> Deref for CustomAutoRooterGuard<'a, T>where T: 'a + CustomTrace,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'a, T> DerefMut for CustomAutoRooterGuard<'a, T>where T: 'a + CustomTrace,

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

Mutably dereferences the value.

impl<'a, T> Drop for CustomAutoRooterGuard<'a, T>where T: 'a + CustomTrace,

fn drop(&mut self)

Executes the destructor for this type.
