Struct OptionChanged 

pub struct OptionChanged {
    pub name: String,
    pub old_value: String,
    pub new_value: String,
    pub source: ChangeSource,
    pub scope: OptionScopeId,
}

An option value changed.

Emitted after any option value is modified via OptionRegistry::set(). Handlers can react to option changes (e.g., re-render, update state).

Example

use reovim_kernel::api::v1::{EventBus, EventResult, events::kernel::OptionChanged};

let bus = EventBus::new();
bus.subscribe::<OptionChanged, _>(100, |event| {
    println!("Option '{}' changed from {} to {}",
        event.name, event.old_value, event.new_value);
    EventResult::Handled
});

Fields

name: String

Full option name that changed.

old_value: String

Previous value.

new_value: String

New value.

source: ChangeSource

Source of the change.

scope: OptionScopeId

Runtime scope where the change was applied (which specific buffer or window).

This is the runtime context, NOT the option’s static scope declaration (see OptionSpec::scope for the capability declaration).

Trait Implementations

impl Clone for OptionChanged

fn clone(&self) -> OptionChanged

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptionChanged

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Event for OptionChanged

fn priority(&self) -> u32

Priority for handler dispatch ordering.

fn batchable(&self) -> bool

Whether this event can be batched with similar events.

impl PartialEq for OptionChanged

fn eq(&self, other: &OptionChanged) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
