cel-cxx-macros

Procedural macros for the cel-cxx crate.

This crate provides derive macros that enable seamless integration of custom Rust types with CEL expressions.

Macros

#[derive(Opaque)]

Automatically implements the necessary traits to use custom Rust types in CEL expressions:

use cel_cxx_macros::Opaque;

#[derive(Opaque, Debug, Clone)]
#[cel_cxx(type = "myapp.User")]
struct User {
    name: String,
    age: i32,
}

impl std::fmt::Display for User {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        write!(f, "User({})", self.name)
    }
}

Add this to your Cargo.toml:

[dependencies]
cel-cxx = { version = "0.1.0", features = ["derive"] }

Or use directly:
