Struct serde_closure::structs::FnOnce

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

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>

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>,

impl<F: Eq> Eq for FnOnce<F>

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

type Output = F::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, 

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.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

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

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FnOnce<F>) -> bool

This method tests for !=.

impl<F: PartialOrd> PartialOrd<FnOnce<F>> 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: &FnOnce<F>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &FnOnce<F>) -> bool

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

fn gt(&self, other: &FnOnce<F>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &FnOnce<F>) -> bool

This method 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.
