Enum serde_hashkey::NeverFloat

pub enum NeverFloat {}

An uninhabitable type for float policies that cannot produce a value of the corresponding type. This is used by RejectFloatPolicy.

Trait Implementations

impl Clone for NeverFloat

fn clone(&self) -> NeverFloat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NeverFloat

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

Formats the value using the given formatter.

impl FloatRepr<f32> for NeverFloat

fn serialize(_: f32) -> Result<Self, Error>

Serialize impl for a floating point value.

fn visit<'de, V>(&self, _: V) -> Result<V::Value, Error>where
    V: Visitor<'de>,

Visit the current value.

impl FloatRepr<f64> for NeverFloat

fn serialize(_: f64) -> Result<Self, Error>

Serialize impl for a floating point value.

fn visit<'de, V>(&self, _: V) -> Result<V::Value, Error>where
    V: Visitor<'de>,

Visit the current value.

impl Hash for NeverFloat

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 Ord for NeverFloat

fn cmp(&self, other: &NeverFloat) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<NeverFloat> for NeverFloat

fn eq(&self, other: &NeverFloat) -> bool

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

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

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

impl PartialOrd<NeverFloat> for NeverFloat

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

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

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

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

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

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

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

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

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

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

impl Serialize for NeverFloat

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

Serialize this value into the given Serde serializer.
