Enum NumberComparisonPolicy 

pub enum NumberComparisonPolicy {
    Conservative,
    Approximate,
}

Policy that controls mixed numeric comparisons.

This policy applies to numeric equality, membership, and range predicates when operands use different numeric representations.

Variants

Conservative

Preserve precision and return “incomparable” for risky mixed comparisons.

This is the historical behavior and therefore the default.

Approximate

Allow lossy f64 fallback for mixed comparisons that are otherwise incomparable under NumberComparisonPolicy::Conservative.

Trait Implementations

impl Clone for NumberComparisonPolicy

fn clone(&self) -> NumberComparisonPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberComparisonPolicy

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

Formats the value using the given formatter.

impl Default for NumberComparisonPolicy

fn default() -> NumberComparisonPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NumberComparisonPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NumberComparisonPolicy

fn eq(&self, other: &NumberComparisonPolicy) -> 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 NumberComparisonPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
