Enum MapKey

pub enum MapKey {
    Bool(bool),
    Int(i64),
    Uint(u64),
    String(ArcStr),
}

CEL map key type.

MapKey represents value types that can be used as CEL map keys. According to the CEL specification, only basic comparable types can be used as map keys.

Supported Key Types

• Bool: Boolean keys
• Int: Signed integer keys
• Uint: Unsigned integer keys
• String: String keys

Examples

use cel_cxx::{MapKey, Value};
use std::collections::HashMap;

let mut map = HashMap::new();

// Different types of keys
map.insert(MapKey::String("name".to_string().into()), Value::String("Alice".to_string().into()));
map.insert(MapKey::Int(42), Value::String("answer".to_string().into()));
map.insert(MapKey::Bool(true), Value::String("yes".to_string().into()));

let map_value = Value::Map(map);

Variants

Bool(bool)

Boolean key

Int(i64)

Signed integer key

Uint(u64)

Unsigned integer key

String(ArcStr)

String key

Implementations

impl MapKey

pub fn kind(&self) -> Kind

Returns the kind of this map key.

Returns the corresponding Kind enum.

pub fn mapkey_type(&self) -> MapKeyType

Returns the type of this map key.

Returns the corresponding MapKeyType enum.

pub fn from_value(value: Value) -> Result<Self, Value>

Creates a map key from a CEL value.

Attempts to convert a Value to MapKey. Only supported basic types can be converted successfully.

Parameters

• value: The CEL value to convert

Returns

• Ok(MapKey): Conversion successful
• Err(Value): Conversion failed, returns original value

Examples

use cel_cxx::{Value, MapKey};

// Successful conversion
let key = MapKey::from_value(Value::String("key".to_string().into())).unwrap();
assert_eq!(key, MapKey::String("key".to_string().into()));

// Failed conversion
let result = MapKey::from_value(Value::List(vec![]));
assert!(result.is_err());

pub fn into_value(self) -> Value

Converts this map key to a CEL value.

Converts MapKey to the corresponding Value.

Examples

use cel_cxx::{MapKey, Value};

let key = MapKey::String("hello".to_string().into());
let value = key.into_value();
assert_eq!(value, Value::String("hello".to_string().into()));
