Struct HResult 

pub struct HResult(pub RawHResult);

A failed (or, rarely, non-S_OK success) HRESULT; the error type of every generated method whose IDL signature returns HRESULT.

Tuple Fields

0: RawHResult

Implementations

impl HResult

pub const NOTIMPL: HResult

pub const NOINTERFACE: HResult

pub const POINTER: HResult

pub const ABORT: HResult

pub const FAIL: HResult

pub const UNEXPECTED: HResult

pub const HANDLE: HResult

pub const INVALIDARG: HResult

pub const INVALIDOPERATION: HResult

pub const OBJECTDISPOSED: HResult

pub fn check(raw: RawHResult) -> Result<(), HResult>

Maps a raw HRESULT to Ok(()) for S_OK and Err for anything else. This mirrors the native sources and MicroCom’s C# proxies, which test hr != S_OK rather than the sign bit.

pub fn from_result(r: Result<(), HResult>) -> RawHResult

Converts a callback result back to the raw value handed to native code.

pub fn name(self) -> Option<&'static str>

Trait Implementations

impl Clone for HResult

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for HResult

impl Debug for HResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for HResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for HResult

impl Error for HResult

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Hash for HResult

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HResult

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
