Struct windows_core::Ref

pub struct Ref<'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.

Implementations§

§

impl<'a, T: Type<T, Default = Option<T>, Abi = *mut c_void>> Ref<'a, T>

pub fn ok(&self) -> Result<&T>

Converts the argument to a Result<&T> reference.
