Derive macros for wa_rs_core protocol types.

This crate provides derive macros for implementing the ProtocolNode trait on structs that represent WhatsApp protocol nodes.

Example

use wa_rs_derive::{ProtocolNode, StringEnum};

/// A query request node.
/// Wire format: `<query request="interactive"/>`
#[derive(ProtocolNode)]
#[protocol(tag = "query")]
pub struct QueryRequest {
    #[attr(name = "request", default = "interactive")]
    pub request_type: String,
}

/// An enum with string representation.
#[derive(StringEnum)]
pub enum MemberAddMode {
    #[str = "admin_add"]
    AdminAdd,
    #[str = "all_member_add"]
    AllMemberAdd,
}
