Struct glib::translate::Borrowed

source ·
pub struct Borrowed<T>(_);
Expand description

Wrapper around values representing borrowed C memory.

This is returned by from_glib_borrow() and ensures that the wrapped value is never dropped when going out of scope.

Borrowed values must never be passed by value or mutable reference to safe Rust code and must not leave the C scope in which they are valid.

Implementations§

source§

impl<T> Borrowed<T>

source

pub fn new(val: T) -> Self

Creates a new borrowed value.

source

pub unsafe fn into_inner(self) -> T

Extracts the contained value.

Safety

The returned value must never be dropped and instead has to be passed to mem::forget() or be directly wrapped in mem::ManuallyDrop or another Borrowed wrapper.
