Struct TransferChain 

pub struct TransferChain { /* private fields */ }

Safety mechanism tracking the ordered sequence of agents in a transfer chain.

The orchestrator creates a new chain per user message and carries it forward through transfers. This prevents infinite handoff loops and enforces depth limits.

Implementations

impl TransferChain

pub const fn new(max_depth: usize) -> Self

Create a new empty chain with the given maximum depth.

pub fn push( &mut self, agent_name: impl Into<String>, ) -> Result<(), TransferError>

Push an agent onto the chain.

Returns Err(TransferError::CircularTransfer) if the agent is already in the chain. Returns Err(TransferError::MaxDepthExceeded) if the chain is at max depth.

pub const fn depth(&self) -> usize

Current depth of the chain (number of agents).

pub fn contains(&self, agent_name: &str) -> bool

Check if an agent is already in the chain.

pub fn chain(&self) -> &[String]

The ordered list of agent names in this chain.
