Expand description
Provides a mechanism for interact with the windows console
This library implements most of the methods in:

Example
Here a quick example of how WinConsole can be use, as you can see we don’t cache the
WinConsole, we use WinConsole::output or WinConsole::input to ensure a call to
get_std_handle and get a fresh handle each time due we can’t know when set_std_handle
could be call.
use win32console::console::WinConsole;
use win32console::input::*;
fn main() {
// Virtual key codes
// https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes
const ESCAPE : u16 = 0x1B;
const BACKSPACE: u16 = 0x08;
const ENTER : u16 = 0x0D;
const SPACE : u16 = 0x20;
loop{
// Get the current input event
if let KeyEvent(key) = WinConsole::input().read_single_input().unwrap(){
// Only check for key down events
if key.key_down{
let char_value = key.u_char;
// Write only if is alphanumeric or punctuation
if char_value.is_ascii_alphanumeric() || char_value.is_ascii_punctuation(){
let mut value : [u8; 1] = [0];
char_value.encode_utf8(&mut value);
WinConsole::output().write_utf8(&value);
}
else{
match key.virtual_key_code {
ESCAPE => { break; },
ENTER => { WinConsole::output().write_utf8("\n".as_bytes()); }
SPACE => { WinConsole::output().write_utf8(" ".as_bytes()); },
BACKSPACE => { WinConsole::output().write_utf8(b"\x08 \x08"); },
_ => {}
}
}
}
}
}
}
