Module codebehind 

Event handlers in a screen’s code-behind — what double-clicking a button in Visual Studio’s designer does: foo.yui’s on_click="play" gets an events::PLAY => play(), arm in the match over click(event) in foo.rs and an empty fn play(), and the editor opens there. An existing arm is just navigated to. A missing foo.rs is created with the usual skeleton (ui_include!, on_event, register).

Structs

HandlerLocation

Where the editor should go.

Functions

add_handler

Adds (or finds) the handler for event in src; None when there’s no event match to add an arm to. Returns the new text and the 1-based line/column of the handler’s body (or the existing arm).

code_behind_path

foo.yui → foo.rs beside it.

const_name

The events:: constant for an event name (yog-cli’s const_name).

ensure_handler

Makes sure yui’s code-behind handles event, writing the file when needed; where to put the caret.

handler_name

A Rust fn name for an event: play, mymod:btn-play → mymod_btn_play.
