Struct js::jsapi::MutableHandle

#[repr(C)]
pub struct MutableHandle<T> {
    pub _base: MutableHandleBase<T>,
    pub ptr: *mut T,
}

Similar to a handle, but the underlying storage can be changed. This is useful for outparams.

If you want to add additional methods to MutableHandle for a specific specialization, define a MutableHandleBase specialization containing them.

Fields

_base: MutableHandleBase<T>

ptr: *mut T

Methods

impl<T> MutableHandle<T>

pub unsafe fn from_marked_location(ptr: *mut T) -> MutableHandle<T>

pub fn handle(&self) -> Handle<T>

pub fn get(&self) -> T where
    T: Copy, 

pub fn set(&self, v: T) where
    T: Copy,
