pub fn total_cmp(&self, other: &f64) -> Ordering

Return the ordering between self and other.

Unlike the standard partial comparison between floating point numbers, this comparison always produces an ordering in accordance to the totalOrder predicate as defined in the IEEE 754 (2008 revision) floating point standard. The values are ordered in the following sequence:

• negative quiet NaN
• negative signaling NaN
• negative infinity
• negative numbers
• negative subnormal numbers
• negative zero
• positive zero
• positive subnormal numbers
• positive numbers
• positive infinity
• positive signaling NaN
• positive quiet NaN.

The ordering established by this function does not always agree with the PartialOrd and PartialEq implementations of f64. For example, they consider negative and positive zero equal, while total_cmp doesn’t.

The interpretation of the signaling NaN bit follows the definition in the IEEE 754 standard, which may not match the interpretation by some of the older, non-conformant (e.g. MIPS) hardware implementations.

Example

struct GoodBoy {
    name: String,
    weight: f64,
}

let mut bois = vec![
    GoodBoy { name: "Pucci".to_owned(), weight: 0.1 },
    GoodBoy { name: "Woofer".to_owned(), weight: 99.0 },
    GoodBoy { name: "Yapper".to_owned(), weight: 10.0 },
    GoodBoy { name: "Chonk".to_owned(), weight: f64::INFINITY },
    GoodBoy { name: "Abs. Unit".to_owned(), weight: f64::NAN },
    GoodBoy { name: "Floaty".to_owned(), weight: -5.0 },
];

bois.sort_by(|a, b| a.weight.total_cmp(&b.weight));

Trait Implementations

impl Clone for NumberAny

fn clone(&self) -> NumberAny

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumberAny

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

Formats the value using the given formatter.

impl Deref for NumberAny

type Target = f64

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for NumberAny

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NumberAny

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

Formats the value using the given formatter.

impl From<NumberAny> for Number

fn from(d: NumberAny) -> Self

Converts to this type from the input type.

impl<'a> FromFormValue<'a> for NumberAny

type Error = NumberError

The associated error which can be returned from parsing. It is a good idea to have the return type be or contain an &'v str so that the unparseable string can be examined after a bad parse.

fn from_form_value(form_value: &'a RawStr) -> Result<Self, Self::Error>

Parses an instance of Self from an HTTP form field value or returns an Error if one cannot be parsed.

fn default() -> Option<Self>

Returns a default value to be used when the form field does not exist. If this returns None, then the field is required. Otherwise, this should return Some(default_value). The default implementation simply returns None.

impl<'a> FromParam<'a> for NumberAny

type Error = NumberError

The associated error to be returned if parsing/validation fails.

fn from_param(param: &'a RawStr) -> Result<Self, Self::Error>

Parses and validates an instance of Self from a path parameter string or returns an Error if parsing or validation fails.

impl Hash for NumberAny

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 PartialEq<NumberAny> for NumberAny

fn eq(&self, other: &NumberAny) -> 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 Serialize for NumberAny

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

Serialize this value into the given Serde serializer.

impl ValidatedWrapper for NumberAny

type Error = NumberError

fn from_string(full_number: String) -> Result<Self, Self::Error>

fn from_str(full_number: &str) -> Result<Self, Self::Error>

impl Eq for NumberAny

impl StructuralPartialEq for NumberAny
