Enum ExprKind 

pub enum ExprKind {
    Constant(Constant),
    Ident(IdentExpr),
    Select(SelectExpr),
    Call(CallExpr),
    List(ListExpr),
    Struct(StructExpr),
    Map(MapExpr),
    Comprehension(ComprehensionExpr),
}

The kind/type of a CEL expression.

ExprKind is an enum representing all possible expression types in CEL. Each variant contains the specific data for that expression type.

Variants

• Constant: Literal constant values
• IdentExpr: Variable or identifier references
• SelectExpr: Field selection or presence tests
• CallExpr: Function or method calls
• ListExpr: List literal expressions
• StructExpr: Struct literal expressions
• MapExpr: Map literal expressions
• ComprehensionExpr: Comprehension expressions for list/map processing

Variants

Constant(Constant)

A constant literal value.

Ident(IdentExpr)

An identifier reference.

Select(SelectExpr)

A field selection or presence test.

Call(CallExpr)

A function or method call.

List(ListExpr)

A list literal.

Struct(StructExpr)

A struct literal.

Map(MapExpr)

A map literal.

Comprehension(ComprehensionExpr)

A comprehension expression.
