Struct PermissionGate 

pub struct PermissionGate { /* private fields */ }

A registry of pending permission requests.

Each in-flight turn holds a shared Arc<PermissionGate>:

• The main loop registers a waiter and awaits via Self::wait
• The ACP bridge layer calls Self::resolve after receiving the client response

Implementations

impl PermissionGate

pub fn new() -> Self

pub async fn wait( &self, id: ToolCallId, cancel: CancellationToken, ) -> PermissionResolution

Register a waiter and await until Self::resolve is called or cancel fires.

When cancel fires, returns PermissionResolution::Cancelled — the main loop handles this as “User cancelled”.

If a waiter already exists for the same id, the old sender is dropped (the old wait receives PermissionResolution::Cancelled, avoiding a hang). This path should theoretically never be hit — the main loop only calls wait once per tool_use.

pub fn resolve(&self, id: &ToolCallId, outcome: PermissionResolution)

Deliver the outcome to the waiter. If id has no waiter (already removed by cancel, or the main loop hasn’t called wait yet), silently no-op — the ACP bridge layer is unaware of main-loop timing, and duplicate or late resolves must not corrupt the turn.

impl Default for PermissionGate

fn default() -> PermissionGate
