Enum PredicateValue 

pub enum PredicateValue {
    Pattern(StringPattern),
    Regex(RegexPattern),
    Subquery(Box<PlanNode>),
}

Right-hand side of a relation predicate.

Mirrors sqry-core::query::types::Value’s String / Regex / Subquery arms that actually flow into the six relation handlers. The IR variant is deliberately narrower than the general-purpose Value — numeric and boolean values never appear on the right of a relation predicate, so they are omitted here.

Variants

Pattern(StringPattern)

Literal string pattern — exact match, glob, prefix, suffix, or contains. Maps to Operator::Equal in graph_eval.

Regex(RegexPattern)

Regex pattern. Maps to Operator::Regex in graph_eval.

Only Predicate::References uses this in the current text syntax (references ~= /foo.*/i), but any relation predicate may accept it at the IR level.

Subquery(Box<PlanNode>)

Nested subquery: callers:(kind:function AND async:true). Evaluated as a distinct PlanNode before the outer relation predicate runs.

Implementations

impl PredicateValue

pub const fn is_subquery(&self) -> bool

Returns true if this value is a PredicateValue::Subquery.

pub fn as_subquery(&self) -> Option<&PlanNode>

Returns the inner PlanNode if this value is a subquery.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PredicateValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for PredicateValue

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 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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PredicateValue

impl StructuralPartialEq for PredicateValue
