Struct SharedIds 

pub struct SharedIds { /* private fields */ }

One allocator, shared by every shard of a runtime.

The lock is taken per allocation rather than for a whole render, so two shards rendering on two cores contend for a few nanoseconds at a time instead of serializing. It is never held across an .await: every method here returns before the caller can suspend.

Implementations

impl SharedIds

pub fn new() -> SharedIds

pub fn channel( &self, shard: ShardId, key: ChannelKey, ) -> Result<ChannelId, Exhausted>

The id for key within shard.

Errors

Exhausted::Channels once every id has been handed out.

pub fn session(&self, occupant: Occupant) -> Result<SessionId, Exhausted>

The session for occupant, stable for as long as the runtime lives.

Errors

Exhausted::Sessions once every session has been handed out.

pub fn allocated_session(&self, occupant: Occupant) -> Option<SessionId>

The session already allocated for occupant, without allocating.

pub fn allocated_channel( &self, shard: ShardId, key: ChannelKey, ) -> Option<ChannelId>

The id already allocated for key within shard, without allocating.

pub fn retain_channels(&self, shard: ShardId, retained: &BTreeSet<ChannelKey>)

Retire the channel identities absent from one shard’s accepted render.

pub fn retire_channel_ids(&self, shard: ShardId, retired: &BTreeSet<ChannelId>)

Retire channel ids one client has accepted as removed.
