Struct HookContext 

pub struct HookContext<'a> {
    pub buffer: &'a mut EditorBuffer,
    pub selection: &'a mut Option<Selection>,
    pub cursor_style: &'a mut CursorStyle,
    pub prompt: &'a mut PromptState,
    pub effects: &'a mut Vec<HookEffect>,
}

Core buffer, syntax, movement, and hook primitives. The mutable editing context passed to editor hooks during events.

prompt is the shared headless input box (bottom bar / command palette): any hook can open it, read submitted input, and fill item rows, with no frontend code. effects collects app-level requests (save/load/quit) that the host drains after each event.

Fields

buffer: &'a mut EditorBuffer

Mutable access to the underlying text buffer.

selection: &'a mut Option<Selection>

Mutable access to the active selection range, if any.

cursor_style: &'a mut CursorStyle

Mutable access to the cursor visual style.

prompt: &'a mut PromptState

Shared headless prompt / input-box state.

effects: &'a mut Vec<HookEffect>

App-level requests for the host to drain after the event.

Implementations

impl<'a> HookContext<'a>

pub fn new( buffer: &'a mut EditorBuffer, selection: &'a mut Option<Selection>, cursor_style: &'a mut CursorStyle, prompt: &'a mut PromptState, effects: &'a mut Vec<HookEffect>, ) -> HookContext<'a>

Creates a new hook context.
