Struct ClosureMut4 

pub struct ClosureMut4<'a, A, B, C, D, R> { /* private fields */ }

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

Implementations

impl<'a, A: CType, B: CType, C: CType, D: CType, R: CType> ClosureMut4<'a, A, B, C, D, R>

pub fn new<Callback>(callback: &'a mut Callback) -> Self

where Callback: FnMut(A, B, C, D) -> R + 'a,

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

impl<'a, A, B, C, D, R: CType> ClosureMut4<'a, A, B, C, D, R>

pub fn code_ptr(&self) -> &FnPtr4<'a, A, B, C, D, R>

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

pub fn from_parts<U>( cif: Cif4<A, B, C, D, R>, callback: CallbackMut4<U, A, B, C, D, R::RetType>, 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. Note that the return type of the callback must follow the libffi implicit extension rules.

impl<'a, A: Copy, B: Copy, C: Copy, D: Copy, R: CType> ClosureMut4<'a, A, B, C, D, R>

pub fn new_with_cif<Callback>( cif: Cif4<A, B, C, D, R>, callback: &'a mut Callback, ) -> Self

where Callback: FnMut(A, B, C, D) -> 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.
