Struct windows_core::OutRef

pub struct OutRef<'a, T: Type<T>>(/* private fields */);
Expand description

A borrowed type with the same memory layout as the type itself that can be used to construct ABI-compatible function signatures.

This is a mutable version of Ref meant to support out parameters.

Implementations§

§

impl<'a, T: Type<T>> OutRef<'a, T>

pub fn is_null(&self) -> bool

Returns true if the argument is null.

pub fn write(self, value: T::Default) -> Result<()>

Overwrites a memory location with the given value without reading or dropping the old value.
