Trait PhpOnceClosure 

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

Available 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.

Dyn Compatibility

This trait is dyn compatible.

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