protocol-droid 0.5.2

//! One `#[server]` block mixing all three marks.
//!
//! The three registrations run in one `into_server`, in source order, against
//! one builder. A case that used each mark in its own impl would not notice a
//! macro that mixed them up — a resource falling through to the tool path is
//! exactly the bug that registers it twice and never derives a schema, and it
//! only shows when a tool and a resource sit in the same block.

/// What the tool answers with.
