Vine/Server/Notification/Support/UnregisterByHandle.rs
1//! Shared helper for provider-unregistration notification atoms.
2//!
3//! Every `unregister_*_provider` wire method does the same three steps:
4//! read the `handle` u32 from the parameter, call
5//! `VineHost::UnregisterProvider`, and emit a tagged dev-log line. This
6//! function centralises that triple so each atom shrinks to a single
7//! delegation call.
8//!
9//! `TypeName` is the provider kind string used in the log line
10//! (e.g. `"authentication"`, `"debug_adapter"`, `"task"`).
