Struct FBox

Source
pub struct FBox<T: ?Sized>(/* private fields */);
Expand description

An owning pointer to a foreign-allocated object.

It doesn’t manage its own allocation, rather, it just drops its content in-place, counting on the Drop impl of the contained type to call the appropriate foreign function to properly dispose of the value.

Named FBox to avoid confusion with the Rust standard library Box. F stands for “foreign”.
