[][src]Struct w32_error::W32Error

#[must_use = "this `W32Error` is unhandled"]#[repr(transparent)]pub struct W32Error(_);

A Windows API error.


impl W32Error[src]

pub const fn new(code: DWORD) -> Self[src]

Wraps an arbitrary error code.


let error = W32Error::new(0);
println!("{}", error);

pub fn from_io_error(other: &Error) -> Option<Self>[src]

Wraps the error code from an io::Error if it has one.


use std::io;
let io_error = io::Error::from_raw_os_error(0);
let opt = W32Error::from_io_error(&io_error);
assert_eq!(opt, Some(W32Error::new(0)));

pub fn last_thread_error() -> Self[src]

Wraps the error code that is currently set for the calling thread.

This is equivalent to calling the Windows API function GetLastError and passing the return value to W32Error::new.


let error = W32Error::last_thread_error();
println!("{}", error);

pub const fn into_inner(self) -> DWORD[src]

Returns the underlying error code wrapped by a W32Error.


assert_eq!(W32Error::new(0).into_inner(), 0);
