Struct windows_result::Error

pub struct Error { /* private fields */ }

An error object consists of both an error code as well as detailed error information for debugging.

Implementations

impl Error

pub const fn empty() -> Self

Creates an error object without any failure information.

pub fn new<T: AsRef<str>>(code: HRESULT, message: T) -> Self

Creates a new error object, capturing the stack and other information about the point of failure.

pub fn from_hresult(code: HRESULT) -> Self

Creates a new error object with an error code, but without additional error information.

pub fn from_win32() -> Self

Creates a new Error from the Win32 error code returned by GetLastError().

pub const fn code(&self) -> HRESULT

The error code describing the error.

pub fn message(&self) -> String

The error message describing the error.

pub fn as_ptr(&self) -> *mut c_void

The error object describing the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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 From<Error> for Error

fn from(from: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(from: Error) -> Self

Converts to this type from the input type.

impl From<Error> for HRESULT

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf16Error> for Error

fn from(_: FromUtf16Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(_: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<HRESULT> for Error

fn from(code: HRESULT) -> Self

Converts to this type from the input type.

impl From<TryFromIntError> for Error

fn from(_: TryFromIntError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
