Struct Refinement 

pub struct Refinement {
    pub binding: String,
    pub predicate: CExpr,
}

Fields

binding: String

The bound variable name from Type{binding | predicate}.

predicate: CExpr

The predicate, stored as a canonical-AST CExpr. The VM interprets it directly via a small tree-walk evaluator — no separate compile pass needed since predicates are pure expressions over a single binding plus, eventually, the surrounding call-site context (slice 3 supports the binding only).

Trait Implementations

impl Clone for Refinement

fn clone(&self) -> Refinement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Refinement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Refinement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Refinement

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
