Enum PredicateValue 

#[non_exhaustive]
pub enum PredicateValue {
    String(String),
    Number(f64),
    Bool(bool),
    Null,
}

Typed predicate value.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

String(String)

String value (quoted in source).

Number(f64)

Numeric value.

Bool(bool)

Boolean value (true / false).

Null

Null literal.

Implementations

impl PredicateValue

pub fn as_str_repr(&self) -> Cow<'_, str>

Convert to a string representation for comparison.

pub fn as_f64(&self) -> Option<f64>

Extract as f64 if numeric, or attempt to parse a string value.

Trait Implementations

impl Clone for PredicateValue

fn clone(&self) -> PredicateValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateValue

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

Formats the value using the given formatter.

impl PartialEq for PredicateValue

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
