Windy

crates.io docs.rs

A Windows strings library that supports AString (ANSI string) and WString (Unicode string).

Features

  • ANSI string(AString)
  • Wide string(WString)
  • AnsiString(ANSI_STRING)
  • UnicodeString(UNICODE_STRING)
  • Interconversion between AString, WString and String.
  • no_std support
  • Macros support

Installation

Add the following lines to your Cargo.toml:

[dependencies]
windy = "0.2.0"

Example

An example of parsing the outputs of cmd.exe.

use windy::AString;
use std::process::Command;

fn main() {
    let o = Command::new("cmd")
        .args(&["/c", "ThisCommandDoesNotExist"])
        .output().unwrap();
    let (stdout, stderr) = unsafe {
        (
            AString::new_unchecked(o.stdout),
            AString::new_unchecked(o.stderr)
        )
    };
    println!("stdout: {:?}", stdout);
    println!("stderr: {:?}", stderr);
}

no_std support

If you don't want to use std, use --no-default-features.

AString and WString are not available when no_std.

Macros support

windy-macros to convert a UTF-8 string to WString or AString at compile time.

[dependencies]
windy = "0.2.0"
windy-macros = "0.1.1"

Example

use windy::WStr;
use windy_macros::wstr;

#[allow(non_snake_case)]
#[link(name = "user32")]
extern "system" {
    pub fn MessageBoxW(
        hWnd: *mut c_void,
        lpText: *const u16,
        lpCaption: *const u16,
        uType: u32,
    ) -> i32;
}

fn main() {
    let text: &WStr = wstr!("World");
    let caption: &WStr = wstr!("CaptionW");
    unsafe {
        MessageBoxW(0 as _, text.as_ptr(), caption.as_ptr(), 0);
    }
}
