Struct PickerClient 

pub struct PickerClient { /* private fields */ }

The Send + Sync handle a host adapter (PH7.4c.2) holds. Cloning it is cheap (an mpsc Sender clone); every clone talks to the same actor / Store, so calls are serialized by the single-consumer loop — the guarantee the !Sync Store needs. Dropping the last clone ends the actor loop (teardown).

Implementations

impl PickerClient

pub fn id(&self) -> PluginId

The host-issued identity of the plugin behind this client — the u32 inside its SourceLayer::Plugin(id) provenance.

pub async fn register_sources( &self, ) -> Result<Vec<NativePickerSourceSpec>, PluginHostError>

OR.5b: drive the guest’s register-picker-sources() and collect every source it declared. Returns a typed host error (PluginGone if the actor has ended, Trap on fuel/epoch/wasm).

An empty list is not an error: a plugin that provides the seam and declares nothing registers nothing, which is what it asked for.

pub async fn init( &self, source: String, ctx: PickerContext, args: Vec<String>, ) -> Result<Result<Vec<CandidatePair>, String>, PluginHostError>

Call the guest’s init(source, ctx, args). The outer result is the host surface; the inner Result<_, String> is the guest’s own WIT result (an Err string is a source that declined to produce candidates).

pub async fn accept( &self, source: String, ctx: PickerContext, routing: RoutingPayload, ) -> Result<Result<PickerAcceptOutcome, String>, PluginHostError>

Call the guest’s accept(source, ctx, routing) — translate the user’s chosen routing token into a typed outcome the host applies.

Trait Implementations

impl Clone for PickerClient

fn clone(&self) -> PickerClient

Returns a duplicate of the value.

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

Performs copy-assignment from source.
