Struct Predicate 

pub struct Predicate {
    pub name: String,
    pub op: Option<PredicateOp>,
    pub value: Option<PredicateValue>,
}

A predicate expression: name, name=value, name^=value, etc.

Fields

name: String

Name to test.

op: Option<PredicateOp>

Comparison operator; None means presence-only check.

value: Option<PredicateValue>

Typed value to compare against, if an operator is present.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl PartialEq for Predicate

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
