Struct FnOnce

pub struct FnOnce<F> { /* private fields */ }

A struct representing a serializable closure, created by the FnOnce macro. Implements traits::FnOnce (and std::ops::FnOnce on nightly), Debug, Serialize and Deserialize, and various convenience traits.

See the readme for examples.

Trait Implementations

impl<F: Clone> Clone for FnOnce<F>

fn clone(&self) -> FnOnce<F>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F> Debug for FnOnce<F>

where F: Debug,

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

Formats the value using the given formatter.

impl<'de, F> Deserialize<'de> for FnOnce<F>

where F: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<F, I: Tuple> FnOnce<I> for FnOnce<F>

where F: FnOnce<I>,

type Output = <F as FnOnce<I>>::Output

The returned type after the call operator is used.

extern "rust-call" fn call_once(self, args: I) -> Self::Output

🔬This is a nightly-only experimental API. (fn_traits)

Performs the call operation.

impl<F: Hash> Hash for FnOnce<F>

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<F: Ord> Ord for FnOnce<F>

fn cmp(&self, other: &FnOnce<F>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<F: PartialEq> PartialEq for FnOnce<F>

fn eq(&self, other: &FnOnce<F>) -> 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<F: PartialOrd> PartialOrd for FnOnce<F>

fn partial_cmp(&self, other: &FnOnce<F>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<F> Serialize for FnOnce<F>

where F: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
