Macro with_context 

macro_rules! with_context {
    ($ctx:expr, $body:expr) => { ... };
}

Macro to run code with request context.

Examples

use pmcp::{with_context, shared::context::RequestContext};
use pmcp::types::RequestId;

// Create a context
let context = RequestContext::new(RequestId::from(123i64))
    .with_user_id("user-456".to_string())
    .with_metadata("region".to_string(), serde_json::json!("us-east-1"));

// Run async code with the context
let result = with_context!(context, {
    // This code runs with the context available
    let current = RequestContext::current().expect("Context should be set");
    assert_eq!(current.user_id, Some("user-456".to_string()));
     
    // Perform some async operation
    async {
        // The context is available in nested async blocks too
        let ctx = RequestContext::current().unwrap();
        assert_eq!(ctx.request_id, RequestId::from(123i64));
        42
    }.await
});

assert_eq!(result, 42);
