Struct TuiBridge 

pub struct TuiBridge {
    pub approval_rx: Receiver<PendingApprovalRequest>,
    pub child_approval_rx: Receiver<PendingChildApproval>,
    pub elicitation_rx: Receiver<PendingElicitation>,
    pub oauth_rx: Receiver<PendingOAuthDisplay>,
    /* private fields */
}

The aggregate wiring point a crates/cli embedder uses: constructs every channel pair once, installs the SENDING halves onto the Agent/ McpClients that need them, and hands the RECEIVING halves to the render loop to poll each frame. See crate::tui::should_activate’s doc comment for why this is only ever built when the TUI is confirmed active — installing these on an agent that no render loop is draining would hang the first Ask-tier prompt or elicitation forever.

Fields

approval_rx: Receiver<PendingApprovalRequest>

Poll this each render frame (try_recv) for a new top-level approval prompt to show.

child_approval_rx: Receiver<PendingChildApproval>

Poll this each render frame for a new child-approval prompt.

elicitation_rx: Receiver<PendingElicitation>

Poll this each render frame for a new elicitation prompt.

oauth_rx: Receiver<PendingOAuthDisplay>

Poll this each render frame for a new OAuth device-code display.

Implementations

impl TuiBridge

pub fn new() -> Self

Build a fresh bridge — four independent channel pairs, all cheap (unbounded mpsc, no background threads spawned here).

pub fn install_on(&self, agent: &mut Agent)

Install this bridge’s top-level-approval and child-approval-factory handlers onto agent. Does NOT touch MCP elicitation — an McpClient needs Self::elicitation_handler installed on IT directly (before the client is consumed into tool registration), which is why that’s a separate method the caller invokes per client, earlier in its own connect sequence.

pub fn elicitation_handler(&self) -> Arc<dyn McpElicitationHandler>

A fresh TuiElicitationHandler wired to this bridge — install on each McpClient via crate::mcp::McpClient::set_elicitation_handler before that client is consumed into tool registration.

pub fn oauth_sender(&self) -> Sender<PendingOAuthDisplay>

The sender half for a one-shot OAuth device-code display push (P5-2 device flow’s on_prompt callback) — see crates/cli’s OAuth login wiring for the call site.

Trait Implementations

impl Default for TuiBridge

fn default() -> Self

Returns the “default value” for a type.
