How to Use Kanata in a Rust Project to Send Keys on Windows?

[VictorLemosR]

Is there a straightforward way to import Kanata into a rust project and utilize its functions for sending keystrokes to applications on Windows?

The key output mechanism isn't quite designed as a library but the primary kanata crate does expose a lib as well as a binary. I don't quite know how that works when consumed from crates.io though 🤔. If you can manage that, you could use these as an entry point:

Create a kanata object with a minimal config, e.g. "(defsrc)(deflayer x)" via:

kanata/src/kanata/mod.rs

Line 416 in d54257a

pub fn new_from_str(cfg: &str) -> Result<Self> {

Then you can call kbd_out to access the key out functions.

kanata/src/kanata/mod.rs

Lines 78 to 80 in d54257a

	pub struct Kanata {
	/// Handle to some OS keyboard output mechanism.
	pub kbd_out: KbdOut,

e.g.

kanata/src/oskbd/windows/llhook.rs

Line 242 in d54257a

pub fn write_key(&mut self, key: OsCode, value: KeyValue) -> Result<(), io::Error> {

The OsCode and KeyValue come from the kanata_parser crate.
