Struct aldrin::DiscovererBuilder

pub struct DiscovererBuilder<'a, Key> { /* private fields */ }

Builder for Discoverers.

See Discoverer for usage examples.

Implementations

impl<'a, Key> DiscovererBuilder<'a, Key>

pub fn new(client: &'a Handle) -> Self

Creates a new DiscovererBuilder.

pub async fn build(self) -> Result<Discoverer<Key>, Error>

Builds the discoverer with the configured set of objects.

pub async fn build_current_only(self) -> Result<Discoverer<Key>, Error>

Builds the discoverer and configures it to consider only current objects and services.

Unlike build, the discoverer will consider only those objects and services that exist already on the bus.

pub fn object( self, key: Key, object: Option<ObjectUuid>, services: impl IntoIterator<Item = ServiceUuid> ) -> Self

Add an object to the discoverer.

The key is an arbitrary value that can later be queried again on DiscovererEvents. It can be used to distinguish events when more than one object has been added.

When specifying an ObjectUuid, the discoverer will match only on that UUID. Otherwise, the discoverer will emit events for every object that matches the set of services.

pub fn any( self, key: Key, services: impl IntoIterator<Item = ServiceUuid> ) -> Self

Registers interest in any object implementing a set of services.

This is a shorthand for calling object(key, None, services).

pub fn specific( self, key: Key, object: impl Into<ObjectUuid>, services: impl IntoIterator<Item = ServiceUuid> ) -> Self

Registers interest in a specific object implementing a set of services.

This is a shorthand for calling object(key, Some(object), services).

Formats the value using the given formatter.
