From bc83a009f655dd3896be4a7cd33cac8032a605f2 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Tue, 23 Dec 2014 11:53:35 -0800 Subject: std: Second pass stabilization for `comm` This commit is a second pass stabilization for the `std::comm` module, performing the following actions: * The entire `std::comm` module was moved under `std::sync::mpsc`. This movement reflects that channels are just yet another synchronization primitive, and they don't necessarily deserve a special place outside of the other concurrency primitives that the standard library offers. * The `send` and `recv` methods have all been removed. * The `send_opt` and `recv_opt` methods have been renamed to `send` and `recv`. This means that all send/receive operations return a `Result` now indicating whether the operation was successful or not. * The error type of `send` is now a `SendError` to implement a custom error message and allow for `unwrap()`. The error type contains an `into_inner` method to extract the value. * The error type of `recv` is now `RecvError` for the same reasons as `send`. * The `TryRecvError` and `TrySendError` types have had public reexports removed of their variants and the variant names have been tweaked with enum namespacing rules. * The `Messages` iterator is renamed to `Iter` This functionality is now all `#[stable]`: * `Sender` * `SyncSender` * `Receiver` * `std::sync::mpsc` * `channel` * `sync_channel` * `Iter` * `Sender::send` * `Sender::clone` * `SyncSender::send` * `SyncSender::try_send` * `SyncSender::clone` * `Receiver::recv` * `Receiver::try_recv` * `Receiver::iter` * `SendError` * `RecvError` * `TrySendError::{mod, Full, Disconnected}` * `TryRecvError::{mod, Empty, Disconnected}` * `SendError::into_inner` * `TrySendError::into_inner` This is a breaking change due to the modification of where this module is located, as well as the changing of the semantics of `send` and `recv`. Most programs just need to rename imports of `std::comm` to `std::sync::mpsc` and add calls to `unwrap` after a send or a receive operation.
