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<(), Error>

Formats the value using the given formatter.

impl<'de, A, R> Deserialize<'de> for Function<A, R>

fn deserialize<D>( deserializer: D, ) -> Result<Function<A, R>, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 as IntoResult<R>>::Error: Error + '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>) -> Object

Converts to this type from the input type.

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

fn from_object(obj: Object) -> Result<Function<A, R>, Error>

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

where A: Hash, R: Hash,

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

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

where A: PartialEq, R: PartialEq,

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.

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
