Struct libffi::high::arity6::Closure6

pub struct Closure6<'a, A, B, C, D, E, F, R> { /* fields omitted */ }

An immutable, typed closure with the given argument and result types.

Methods

impl<'a, A: CType, B: CType, C: CType, D: CType, E: CType, F: CType, R: CType> Closure6<'a, A, B, C, D, E, F, R>

pub fn new<Callback>(callback: &'a Callback) -> Self where
    Callback: Fn(A, B, C, D, E, F) -> R + 'a, 

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

impl<'a, A, B, C, D, E, F, R> Closure6<'a, A, B, C, D, E, F, R>

pub fn code_ptr(
    &self
) -> &extern "C" fn(_: A, _: B, _: C, _: D, _: E, _: F) -> R

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

pub fn from_parts<U>(
    cif: Cif6<A, B, C, D, E, F, R>,
    callback: Callback6<U, A, B, C, D, E, F, R>,
    userdata: &'a 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, B: Copy, C: Copy, D: Copy, E: Copy, F: Copy, R> Closure6<'a, A, B, C, D, E, F, R>

pub fn new_with_cif<Callback>(
    cif: Cif6<A, B, C, D, E, F, R>,
    callback: &'a Callback
) -> Self where
    Callback: Fn(A, B, C, D, E, F) -> 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.
