Struct libffi::high::arity1::ClosureMut1

pub struct ClosureMut1<'a, A, R> { /* fields omitted */ }

A mutable, typed closure with the given argument and result types.

Methods

impl<'a, A: CType, R: CType> ClosureMut1<'a, A, R>

pub fn new<Callback>(callback: &'a mut Callback) -> Self where
    Callback: FnMut(A) -> R + 'a, 

Constructs a typed closure callable from C from a Rust closure.

impl<'a, A, R> ClosureMut1<'a, A, R>

pub fn code_ptr(&self) -> &extern "C" fn(_: A) -> R

Gets the C code pointer that is used to invoke the closure.

pub fn from_parts<U>(
    cif: Cif1<A, R>,
    callback: CallbackMut1<U, A, R>,
    userdata: &'a mut U
) -> Self

Constructs a typed closure callable from C from a CIF describing the calling convention for the resulting function, a callback for the function to call, and userdata to pass to the callback.

impl<'a, A: Copy, R> ClosureMut1<'a, A, R>

pub fn new_with_cif<Callback>(
    cif: Cif1<A, R>,
    callback: &'a mut Callback
) -> Self where
    Callback: FnMut(A) -> R + 'a, 

Constructs a typed closure callable from C from a CIF describing the calling convention for the resulting function and the Rust closure to call.
