Implementations

impl TransientSourceRegistry

pub fn new() -> Self

pub fn register( &self, name: impl Into<String>, builder: impl Fn(&TransientContext) -> TransientSpec + Send + Sync + 'static, )

Register a named synchronous builder — a native menu, whose rows are a pure function of the open context. Re-registering a name overwrites the previous entry (last writer wins), matching PickerRegistry::register’s semantics.

pub fn register_async( &self, name: impl Into<String>, builder: impl Fn(&TransientContext) -> TransientBuildFuture + Send + Sync + 'static, )

TR.2: register a named builder that answers a TransientBuildFuture — the guest-backed shape. The host parks on the future and seats the menu when it lands.

pub fn unregister(&self, name: &str) -> bool

TR.2: drop the builder registered under name, reporting whether one was there. The teardown half of register_async — an unloaded plugin’s menu name must stop resolving, or Effect::OpenTransient would keep reaching a client whose actor is gone and report a host error instead of “unknown source”.

pub fn build( &self, name: &str, ctx: &TransientContext, ) -> Option<TransientBuild>

Build the named transient for the place it was opened from, or None if no builder is registered under name.

MG.23h: ctx is supplied by the renderer at open time rather than by whatever emitted Effect::OpenTransient. That is what makes every path uniformly context-aware — the chord, the ex-command (whose ExCommandContext carries no buffer), and any future plugin-emitted open. Resolving it at emit time instead would leave all but the chord looking at nothing.

pub fn build_ready( &self, name: &str, ctx: &TransientContext, ) -> Option<TransientSpec>

build for a caller that can only handle a synchronous answer — tests and native call sites that predate TR.2. A guest-backed name answers None here rather than blocking.
