ComparePredicate

Implementations

impl ComparePredicate

pub fn with_coercion( field: impl Into<String>, op: CompareOp, value: Value, coercion: CoercionId, ) -> Self

Construct a comparison predicate with an explicit coercion policy.

This is the low-level predicate AST constructor used by SQL lowering, generated index predicates, and tests that need a precise coercion contract. It does not validate field existence, operator/literal compatibility, or schema admissibility; those checks belong to predicate validation and query planning.

pub fn eq(field: String, value: Value) -> Self

Build Eq comparison.

pub fn ne(field: String, value: Value) -> Self

Build Ne comparison.

pub fn lt(field: String, value: Value) -> Self

Build Lt comparison.

pub fn lte(field: String, value: Value) -> Self

Build Lte comparison.

pub fn gt(field: String, value: Value) -> Self

Build Gt comparison.

pub fn gte(field: String, value: Value) -> Self

Build Gte comparison.

pub fn in_(field: String, values: Vec<Value>) -> Self

Build In comparison.

pub fn not_in(field: String, values: Vec<Value>) -> Self

Build NotIn comparison.

pub fn field(&self) -> &str

Borrow the compared field name.

pub const fn op(&self) -> CompareOp

Return the compare operator.

pub const fn value(&self) -> &Value

Borrow the compared literal value.

pub const fn coercion(&self) -> &CoercionSpec

Borrow the comparison coercion policy.

Trait Implementations

impl Clone for ComparePredicate

fn clone(&self) -> ComparePredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComparePredicate

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

Formats the value using the given formatter.

impl Eq for ComparePredicate

impl PartialEq for ComparePredicate

fn eq(&self, other: &ComparePredicate) -> 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.
