Trait Held 

pub trait Held {
    // Provided method
    fn wanted(&self) -> bool { ... }
}

A hold of the exchanges’ lock, as a Hold gives it: let go when dropped.

Provided Methods

fn wanted(&self) -> bool

Whether an exchange waits for the lock now (a dose’s alarm): the hold then ends after the copy it places (review of part 4, D-1b).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
