Struct windows::HRESULT[−][src]

#[repr(transparent)]
#[must_use]
pub struct HRESULT(pub u32);

Expand description

A primitive error code value returned by most COM functions.

Implementations

impl HRESULT[src]

pub fn is_ok(self) -> bool[src]

Returns true if self is a success code.

pub fn is_err(self) -> bool[src]

Returns true if self is a failure code.

pub fn unwrap(self)[src]

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<()>[src]

Converts the HRESULT to Result<()>.

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

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,

[src]

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>[src]

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

pub fn from_thread() -> Self[src]

Retrieves the error code stored on the calling thread.

pub fn from_win32(error: u32) -> Self[src]

Creates a failure code with the provided win32 error code.

This is equivalent to HRESULT_FROM_WIN32.

pub fn message(&self) -> String[src]

The error message describing the error.
