Struct win_sys::Error

source · [−]

pub struct Error { /* private fields */ }

Expand description

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

Implementations

source

impl Error

source

pub const OK: Error

An error object without any failure information.

source

pub fn new(code: HRESULT, message: HSTRING) -> Error

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

source

pub fn from_win32() -> Error

source

pub const fn code(&self) -> HRESULT

The error code describing the error.

source

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

The error information describing the error.

source

pub fn message(&self) -> HSTRING

The error message describing the error.

source

pub fn win32_error(&self) -> Option<WIN32_ERROR>

Returns the win32 error code if the underlying HRESULT’s facility is win32

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
