Struct windows::Error

pub struct Error { /* fields omitted */ }

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

Implementations

impl Error

pub fn new(code: HRESULT, message: &str) -> Self

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

pub fn fast_error(code: HRESULT) -> Self

pub fn code(&self) -> HRESULT

The error code describing the error.

pub fn info(&self) -> &Option<IRestrictedErrorInfo>

The error information describing the error.

pub fn message(&self) -> String

The error message describing the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

pub 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

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for HRESULT

fn from(error: Error) -> Self

Performs the conversion.

impl From<HRESULT> for Error

fn from(code: HRESULT) -> Self

Performs the conversion.

impl PartialEq<Error> 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: &Error) -> bool

This method tests for !=.
