Implementations

impl HRESULT

pub const fn is_ok(self) -> bool

Returns true if self is a success code.

pub const fn is_err(self) -> bool

Returns true if self is a failure code.

pub fn unwrap(self)

Asserts that self is a success code.

This will invoke the panic! macro if self is a failure code and display the HRESULT value for diagnostics.

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

Converts the HRESULT to Result<()>.

pub fn and_some<T: Interface>(self, some: Option<T>) -> Result<T>

Returns the Option as a Result if the option is a Some value, returning a suitable error if not.

pub fn and_then<F, T>(self, op: F) -> Result<T> where
F: FnOnce() -> T,

Calls op if self is a success code, otherwise returns HRESULT converted to Result<T>.

pub unsafe fn from_abi<T: Abi>(self, abi: T::Abi) -> Result<T>

Safety

If the Result is Ok converts the T::Abi into T.

pub fn message(&self) -> HSTRING

The error message describing the error.
