Struct SendCap 

pub struct SendCap<P: Permission> { /* private fields */ }

A thread-safe capability token that can be sent across threads.

Created explicitly via Cap::make_send. Unlike Cap<P>, this implements Send + Sync, making it usable with std::thread::spawn, tokio::spawn, Arc, etc.

Example

let root = test_root();
let send_cap = root.grant::<FsRead>().make_send();

std::thread::spawn(move || {
    let _cap = send_cap.as_cap();
    // use cap in this thread
}).join().unwrap();

Implementations

impl<P: Permission> SendCap<P>

pub fn as_cap(&self) -> Cap<P>

Returns a new Cap<P> from this send-capable token.

This creates a fresh Cap (not a reference cast) — safe because both types are zero-sized proof tokens.
