Struct OpaqueType

pub struct OpaqueType {
    pub name: String,
    pub parameters: Vec<ValueType>,
}

Opaque type for user-defined types.

Opaque types allow you to integrate custom Rust types into CEL expressions. They are identified by name and can have type parameters for generic types.

Examples

use cel_cxx::*;

// Simple opaque type: MyType
let simple = OpaqueType::new("MyType", vec![]);

// Generic opaque type: MyGeneric<string, int>
let generic = OpaqueType::new("MyGeneric", vec![ValueType::String, ValueType::Int]);

Fields

name: String

The name of the opaque type.

parameters: Vec<ValueType>

Type parameters for generic opaque types.

Implementations

impl OpaqueType

pub fn new<S: Into<String>>(name: S, parameters: Vec<ValueType>) -> Self

Creates a new opaque type with the given name and type parameters.

Arguments

• name - The name of the opaque type
• parameters - Type parameters for generic opaque types

Examples

use cel_cxx::*;

// Simple opaque type
let simple = OpaqueType::new("MyType", vec![]);

// Generic opaque type
let generic = OpaqueType::new("Container", vec![ValueType::String]);

pub fn name(&self) -> &str

Returns the name of this opaque type.

Examples

use cel_cxx::*;

let opaque_type = OpaqueType::new("MyType", vec![]);
assert_eq!(opaque_type.name(), "MyType");

pub fn parameters(&self) -> &[ValueType]

Returns the type parameters of this opaque type.

Examples

use cel_cxx::*;

let opaque_type = OpaqueType::new("Container", vec![ValueType::Int, ValueType::String]);
assert_eq!(opaque_type.parameters().len(), 2);

Trait Implementations

impl Clone for OpaqueType

fn clone(&self) -> OpaqueType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpaqueType

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

Formats the value using the given formatter.

impl Display for OpaqueType

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

Formats the value using the given formatter.

impl From<OpaqueType> for ValueType

fn from(value: OpaqueType) -> Self

Converts to this type from the input type.

impl Hash for OpaqueType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OpaqueType

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