Trait ext_php_rs::closure::PhpOnceClosure

pub trait PhpOnceClosure {
    fn into_closure(self) -> Closure;
}

This is supported on crate feature closure only.

Implemented on FnOnce types which can be used as PHP closures. See Closure.

Internally, this trait should wrap the FnOnce closure inside a FnMut closure, and prevent the user from calling the closure more than once.

Required methods

fn into_closure(self) -> Closure

Converts the Rust FnOnce closure into a FnMut closure, and then into a PHP closure.
