Struct serde_hashkey::RejectFloatPolicy

pub struct RejectFloatPolicy(_);

A float serialization policy which rejects any attempt to serialize a float with an error. This policy is used by the to_key function.

Examples

use serde_hashkey::{Key, Float, to_key};

assert!(to_key(&"John Doe").is_ok());
assert!(to_key(&42.42f32).is_err());

Trait Implementations

impl Clone for RejectFloatPolicy

fn clone(&self) -> RejectFloatPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RejectFloatPolicy

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

Formats the value using the given formatter.

impl FloatPolicy for RejectFloatPolicy

type F32 = NeverFloat

The type encapsulating a 32-bit float, or f32.

type F64 = NeverFloat

The type encapsulating a 64-bit float, or f64.

impl Hash for RejectFloatPolicy

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 RejectFloatPolicy

fn cmp(&self, other: &RejectFloatPolicy) -> 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<RejectFloatPolicy> for RejectFloatPolicy

fn eq(&self, other: &RejectFloatPolicy) -> 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<RejectFloatPolicy> for RejectFloatPolicy

fn partial_cmp(&self, other: &RejectFloatPolicy) -> 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.
