Struct Relay 

Source 
pub struct Relay;
Expand description

A readable stream handle - can be subscribed to and piped from. A typed, heterogeneous relay with lossless delivery and completion tracking. Relay namespace for creating channels.

Use Relay::channel() to create a new relay channel.

Implementations§

Source§

impl Relay

Source

pub fn channel() -> (RelaySender, RelayReceiver)

Create a new relay channel with explicit ownership semantics.

Returns (RelaySender, RelayReceiver) where:

  • RelaySender is the sole owner (not Clone) - dropping it closes the channel
  • RelayReceiver can be cloned for multiple subscribers
  • Use tx.weak() to get a WeakSender for sending without ownership

This is the recommended way to create relays as it enforces clear lifecycle ownership.

Source

pub fn channel_with_size(channel_size: usize) -> (RelaySender, RelayReceiver)

Create a relay channel with custom buffer size.
