The core change here is the following: ```rust fn write_to_pty(&self, input: impl Into<Vec<u8>>); // into fn write_to_pty(&self, input: impl Into<Cow<'static, [u8]>>); ``` This matches the trait bounds that's used by the Alacritty crate. We are now allowed to effectively pass `&'static str` instead of always needing a `String`. The main benefit comes from making the `to_esc_str` function return a `Cow<'static, str>` instead of `String`. We save an allocation in the following instances: - When the user presses any special key that isn't alphanumerical (in the terminal) - When the uses presses any key while a modifier is active (in the terminal) - When focusing/un-focusing the terminal - When completing or undoing a terminal transaction - When starting a terminal assist This basically saves us an allocation on **every key** press in the terminal. NOTE: This same optimization can be done for **nearly all** keypresses in the entirety of Zed by changing the signature of the `Keystroke` struct in gpui. If the Zed team is interested in a PR for it, let me know. Release Notes: - N/A |
