Enum Value

pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Uint(u64),
    Double(f64),
    String(ArcStr),
    Bytes(ArcBytes),
    Struct(()),

}

Main CEL value type.

Value is the core value type of the CEL expression system, supporting all data types defined by the CEL specification. Each variant corresponds to a CEL basic type or composite type.

CEL Type Mapping

• Null → CEL null
• Bool → CEL bool
• Int → CEL int (64-bit signed integer)
• Uint → CEL uint (64-bit unsigned integer)
• Double → CEL double (64-bit floating point)
• String → CEL string
• Bytes → CEL bytes
• Duration → CEL duration (Protocol Buffers Duration)
• Timestamp → CEL timestamp (Protocol Buffers Timestamp)
• List → CEL list
• Map → CEL map
• Type → CEL type (type value)
• Error → CEL error
• Opaque → Opaque custom types
• Optional → Optional value type

Examples

use cel_cxx::Value;

// Basic types
let null_val = Value::Null;
let bool_val = Value::Bool(true);
let int_val = Value::Int(-42);
let uint_val = Value::Uint(42u64);
let double_val = Value::Double(3.14);
let string_val = Value::String("hello".to_string().into());
let bytes_val = Value::Bytes(vec![1, 2, 3].into());

// Time types
let duration = Value::Duration(chrono::Duration::seconds(30));
let timestamp = Value::Timestamp(chrono::Utc::now());

// Container types
let list = Value::List(vec![Value::Int(1), Value::Int(2)]);

Implementations

impl Value

pub fn kind(&self) -> Kind

Returns the kind of this value.

Returns the corresponding Kind enum for fast type checking.

Examples

use cel_cxx::{Value, Kind};

let val = Value::String("hello".to_string().into());
assert_eq!(val.kind(), Kind::String);

let val = Value::List(vec![]);
assert_eq!(val.kind(), Kind::List);

pub fn value_type(&self) -> ValueType

Returns the concrete type of this value.

Returns detailed ValueType information including generic parameters. For container types (List, Map), infers element or key-value types.

Type Inference Rules

• List: Returns specific List<T> if all elements have the same type; otherwise List<dyn>
• Map: Infers key and value types; uses dyn types if inconsistent
• Optional: Infers type from contained value; uses Optional<dyn> for empty values

Examples

use cel_cxx::{Value, ValueType, ListType};

let val = Value::String("hello".to_string().into());
assert_eq!(val.value_type(), ValueType::String);

// Homogeneous list
let list = Value::List(vec![Value::Int(1), Value::Int(2)]);
assert_eq!(list.value_type(), ValueType::List(ListType::new(ValueType::Int)));

// Heterogeneous list
let mixed_list = Value::List(vec![Value::Int(1), Value::String("hello".to_string().into())]);
assert_eq!(mixed_list.value_type(), ValueType::List(ListType::new(ValueType::Dyn)));
