Struct Win32Error 

pub struct Win32Error(/* private fields */);

A WIN32_ERROR wrapper.

Implementations

impl Win32Error

pub fn is_ok(self) -> bool

Tells whether the error is ERROR_SUCCESS.

pub fn is_err(self) -> bool

Tells whether the error is not ERROR_SUCCESS.

pub fn code_number(self) -> u32

The numeric error code.

Example

use windows_ccd::Win32Error;
use windows_ccd::windows::ERROR_INVALID_PARAMETER;

let e = Win32Error::from(ERROR_INVALID_PARAMETER);
assert_eq!(e.code_number(), 87);

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

The name and description of the error.

Example

use windows_ccd::Win32Error;
use windows_ccd::windows::ERROR_INVALID_PARAMETER;

let e = Win32Error::from(ERROR_INVALID_PARAMETER);
let (error_code_str, error_text) = e.code_str_and_text().unwrap();
assert_eq!(error_code_str, "ERROR_INVALID_PARAMETER");
assert_eq!(error_text, "The combination of parameters and flags that are specified is invalid.");

Trait Implementations

impl Clone for Win32Error

fn clone(&self) -> Win32Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Win32Error

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

Formats the value using the given formatter.

impl Display for Win32Error

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

Formats the value using the given formatter.

impl From<WIN32_ERROR> for Win32Error

fn from(value: WIN32_ERROR) -> Self

Converts to this type from the input type.

impl From<i32> for Win32Error

fn from(value: i32) -> Self

Converts to this type from the input type.

impl From<u32> for Win32Error

fn from(value: u32) -> Self

Converts to this type from the input type.

impl PartialEq for Win32Error

fn eq(&self, other: &Win32Error) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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