Struct PluginRegistry 

pub struct PluginRegistry<App: 'static = ()> { /* private fields */ }

Holds every registered Plugin and runs their hooks at the right times.

App is the optional application-wide shared state type; plugins may read it but never mutate it directly. A registry is cheap to clone (inner Rc).

Implementations

impl<App: 'static> PluginRegistry<App>

pub fn new() -> Self

Creates an empty registry.

pub fn register<P: Plugin + 'static>(&mut self, plugin: P) -> &'static str

where P::State: Default,

Registers a plugin, storing its initial state. Returns the plugin’s name so callers can wire up its Context if desired. Panics if a plugin with the same name is already registered.

pub fn register_with_state<P: Plugin + 'static>( &mut self, plugin: P, state: P::State, ) -> &'static str

Registers a plugin together with an existing shared state value.

pub fn run_before_render_hooks(&self, app: Option<&App>)

Runs every plugin’s on_before_render hook.

pub fn run_render_hooks(&self, app: Option<&App>)

Runs every plugin’s on_render hook, then advances the render counter.

pub fn run_shutdown_hooks(&self, app: Option<&App>)

Runs every plugin’s on_shutdown hook.

pub fn len(&self) -> usize

Number of registered plugins.

pub fn is_empty(&self) -> bool

Whether the registry has no plugins.

pub fn bump_render_count(&self)

Advances the internal render counter (called by the host once per completed render). run_render_hooks does not do this itself so the count is stable for the duration of a render.

Trait Implementations

impl<App: 'static> Clone for PluginRegistry<App>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<App: 'static> Default for PluginRegistry<App>

fn default() -> Self

Returns the “default value” for a type.
