Enum DoubleConstraint 

pub enum DoubleConstraint {
    Always,
    Never,
    Min {
        n: f64,
    },
    Max {
        n: f64,
    },
    Range {
        min: f64,
        max: f64,
    },
    And {
        children: Vec<Self>,
    },
    Or {
        children: Vec<Self>,
    },
    Not {
        child: Box<Self>,
    },
}

Double-precision float constraint.

No InSet or Multiple — those are ill-defined on floats (equality is brittle, modulo is non-sensical).

Variants

Always

Always satisfied.

Never

Never satisfied.

Min

value >= n.

Fields

n: f64

Inclusive lower bound.

Max

value <= n.

Fields

n: f64

Inclusive upper bound.

Range

min <= value <= max.

Fields

min: f64

Inclusive lower bound.

max: f64

Inclusive upper bound.

And

All children must hold.

Fields

children: Vec<Self>

Conjuncts.

Or

At least one child must hold.

Fields

children: Vec<Self>

Disjuncts.

Not

Child must not hold.

Fields

child: Box<Self>

The negated child.

Implementations

impl DoubleConstraint

pub fn test(&self, value: f64) -> bool

Test a candidate value. NaN inputs always fail.

pub fn and(self, rhs: Self) -> Self

Conjunction, flattening nested And.

pub fn or(self, rhs: Self) -> Self

Disjunction, flattening nested Or.

pub fn canonicalize(self) -> Self

Same rule set as IntConstraint::canonicalize.

pub fn canonical_bytes(&self) -> Vec<u8>

Canonical byte form of this constraint as written.

pub fn fingerprint(&self) -> Fingerprint

Canonical fingerprint — auto-canonicalises first. NaN leaves are folded to the canonical quiet-NaN pattern before hashing.

Trait Implementations

impl Clone for DoubleConstraint

fn clone(&self) -> DoubleConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DoubleConstraint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DoubleConstraint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Not for DoubleConstraint

type Output = DoubleConstraint

The resulting type after applying the ! operator.

fn not(self) -> Self

Performs the unary ! operation.

impl PartialEq for DoubleConstraint

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
