Function tfc::parse_byte_command

pub fn parse_byte_command(
    buf: &[u8]
) -> Result<(Command, usize), ParseByteCommandError>

Parse a sequence of bytes to create a Command.

The first byte in the buffer must be a CommandCode. This identifies the command and its arguments. Following the command identifier is a sequence of bytes that encode the arguments of the command. Key and MouseButton are single bytes. For integer arguments (used for moving the mouse and scrolling), 16-bit signed big-endian integers are used.

Returns the command and the number of bytes that were read from the buffer.

Arguments

• buf - The byte buffer to read from.

Examples

let bytes = &[
    tfc::CommandCode::MouseMoveRel as u8, 255, 214, 0, 64,
    tfc::CommandCode::KeyClick as u8, tfc::Key::K as u8
];

let (command, len) = tfc::parse_byte_command(bytes).unwrap();
assert_eq!(len, 5);
assert_eq!(command, tfc::Command::MouseMoveRel(-42, 64));

let bytes = &bytes[len..];
let (command, len) = tfc::parse_byte_command(bytes).unwrap();
assert_eq!(len, 2);
assert_eq!(command, tfc::Command::KeyClick(tfc::Key::K));
