Trait Channel 

pub trait Channel: Send {
    // Required methods
    fn recv<'life0, 'async_trait>(
        &'life0 mut self,
    ) -> Pin<Box<dyn Future<Output = Option<ChannelMessage>> + Send + 'async_trait>>
       where 'life0: 'async_trait,
             Self: 'async_trait;
    fn send<'life0, 'async_trait>(
        &'life0 self,
        output: ChannelOutput,
    ) -> Pin<Box<dyn Future<Output = Result<(), ChannelError>> + Send + 'async_trait>>
       where 'life0: 'async_trait,
             Self: 'async_trait;
}

Re-export channel types from bob_core for convenience. Abstract channel for multi-endpoint agent interaction.

Each channel implementation handles the transport-specific details of receiving user input and delivering agent output. The agent loop is decoupled from any specific transport.

Implementing a Channel

use bob_core::channel::{Channel, ChannelMessage, ChannelOutput, ChannelError};

struct MyTelegramChannel { /* ... */ }

#[async_trait::async_trait]
impl Channel for MyTelegramChannel {
    async fn recv(&mut self) -> Option<ChannelMessage> {
        // Poll Telegram API for new messages...
    }

    async fn send(&self, output: ChannelOutput) -> Result<(), ChannelError> {
        // Send via Telegram Bot API...
        Ok(())
    }
}

Required Methods

fn recv<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Option<ChannelMessage>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Receive the next user input message.

Returns None when the channel is closed (e.g. user disconnected, stdin EOF, or graceful shutdown).

fn send<'life0, 'async_trait>( &'life0 self, output: ChannelOutput, ) -> Pin<Box<dyn Future<Output = Result<(), ChannelError>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Send an agent response back to the user.
