Crate log_args_runtime

log-args-runtime

This crate provides runtime support for the log-args procedural macro crate. It exposes thread-local storage for propagating structured logging context (such as parent spans) at runtime. This crate is used internally by macro-generated code and is not intended for direct use by end users.

Usage

Most users do not need to interact with this crate directly. If you are developing custom integrations, you can use the __PARENT_LOG_ARGS thread-local variable to set or retrieve the current parent log context.

use log_args_runtime::__PARENT_LOG_ARGS;

__PARENT_LOG_ARGS.with(|parent| {
    *parent.borrow_mut() = Some("parent-context".to_string());
});

__PARENT_LOG_ARGS.with(|parent| {
    if let Some(ctx) = &*parent.borrow() {
        println!("Current parent context: {}", ctx);
    }
});
