Struct Function

pub struct Function<A, R> { /* private fields */ }

A wrapper around a Lua reference to a function stored in the Lua registry.

Implementations

impl<A, R> Function<A, R>

where F: Fn(A) -> O + 'static, A: Poppable, O: IntoResult<R>, R: Pushable, O::Error: StdError + 'static,

pub fn from_fn_mut<F, O>(fun: F) -> Self

where F: FnMut(A) -> O + 'static, A: Poppable, O: IntoResult<R>, R: Pushable, O::Error: StdError + 'static,

pub fn from_fn_once<F, O>(fun: F) -> Self

where F: FnOnce(A) -> O + 'static, A: Poppable, O: IntoResult<R>, R: Pushable, O::Error: StdError + 'static,

where A: Pushable, R: Poppable,

Trait Implementations

impl<A: Clone, R: Clone> Clone for Function<A, R>

fn clone(&self) -> Function<A, R>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A, R> Debug for Function<A, R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<A, R, F, O> From<F> for Function<A, R>

where F: Fn(A) -> O + 'static, A: Poppable, O: IntoResult<R>, R: Pushable, O::Error: StdError + 'static,

fn from(fun: F) -> Function<A, R>

Converts to this type from the input type.

impl<A, R> From<Function<A, R>> for Object

fn from(fun: Function<A, R>) -> Self

Converts to this type from the input type.

impl<A, R> FromObject for Function<A, R>

fn from_object(obj: Object) -> Result<Self, Error>

impl<A: Hash, R: Hash> Hash for Function<A, R>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<A: PartialEq, R: PartialEq> PartialEq for Function<A, R>

fn eq(&self, other: &Function<A, R>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<A, R> Poppable for Function<A, R>

unsafe fn pop(state: *mut State) -> Result<Self, Error>

Pops the value at the top of the stack.

impl<A, R> Pushable for Function<A, R>

unsafe fn push(self, state: *mut State) -> Result<c_int, Error>

Pushes all its values on the Lua stack, returning the number of values that it pushed.
