Struct windows::Weak[−][src]

pub struct Weak<I: Interface>(_, _);
Expand description

Weak holds a non-owning reference to an object.

pub fn new() -> Self[src]

Creates a new Weak object without any backing object.

pub fn upgrade(&self) -> Option<I>[src]

Attempts to upgrade the weak reference to a strong reference.
