libuv and default rtio implementation. libuv and default rtio implementation. Bindings to libuv, along with the default implementation of std::rt::rtio.

UV types consist of the event loop (Loop), Watchers, Requests and Callbacks.

Watchers and Requests encapsulate pointers to uv handles, which have subtyping relationships with each other. This subtyping is reflected in the bindings with explicit or implicit coercions. For example, an upcast from TcpWatcher to StreamWatcher is done with tcp_watcher.as_stream(). In other cases a callback on a specific type of watcher will be passed a watcher of a supertype.

Currently all use of Request types (connect/write requests) are encapsulated in the bindings and don't need to be dealt with by the caller.

Safety note

Due to the complex lifecycle of uv handles, as well as compiler bugs, this module is not memory safe and requires explicit memory management, via close and delete methods.
