CHANGELOG.md

v0.3.0 (unreleased)

• Complete rewrite of the internals in an attempt to make it easier to port.
• The methods on Config are now implementation specific.
• Removed the AsFd implementation for Ring as that might not always be possible to provide.
• The net::SocketAddress is now implemented for the socket address types for in the standard library, not in libc.
• net::Connect no longer implements Extract as all socket address types in the library are Copy.
• The BufSlice and BufMutSlice types now use IoSlice and IoMutSlice as wrapper around libc::iovec.
• The msg module now uses the MsgData type as type for message data, instead of u32 (though MsgData is also u32).
• process::ReceiveSignals is now a proper AsyncIter.

v0.2.2

• Fix possible overflow in ReadBuf::release https://github.com/Thomasdezeeuw/a10/commit/79078cb9a2f4222eb184588ab1b05c37ad5f5507.
• Don't close direct descriptor using close(2) https://github.com/Thomasdezeeuw/a10/commit/a51984404c00beb6cecf4419842860fe41d23154.

v0.2.1

• Added AsyncFd::truncate https://github.com/Thomasdezeeuw/a10/commit/6cd74479264cbd230e47b9d2a572a75aab4d83b1.
• Synchronously close fd if it can't be done asynchronously due to a full queue https://github.com/Thomasdezeeuw/a10/commit/42565a387be884921e5300cf3fc4f833e178906d.
• Exports Cancel at the root of the crate https://github.com/Thomasdezeeuw/a10/commit/4b91d3f1fcd8502076150bfb12853e9f08b1bdc4.

This is used when a Future is dropped before it's operation is complete. https://github.com/Thomasdezeeuw/a10/commit/629c25e3883d2eedffe77eda4937cc50842f4c32, https://github.com/Thomasdezeeuw/a10/commit/f1ff3e4bc374136fef3b0d71f5e9ba7e77cea3b0, https://github.com/Thomasdezeeuw/a10/commit/fbc6d8478cb89a179a6c72a1dab9fb1406dfa123.

v0.2.0

This release adds support for direct descriptors, which are io_uring specific file descriptors. Direct descriptor have lower overhead, but an only be used in io_uring operations, not regular system calls. It is possible to convert a direct descriptor into a file descriptor and vica versa.

• AsyncFd now has a generic parameter D that supports either a regular file descriptor (fd::File) or a direct desctiptor (fd::Direct). #102, https://github.com/Thomasdezeeuw/a10/commit/03fe635399f3e453b7b707e080ba239e498e5416, https://github.com/Thomasdezeeuw/a10/commit/2682bbb6b4e4d18490bf954abc1342ddca003860, https://github.com/Thomasdezeeuw/a10/commit/b7aafeaa9f615324c4168bc377625b95a14766de, https://github.com/Thomasdezeeuw/a10/commit/1684af7b2dc3880a0db57dd3dc75184aa66057b8, https://github.com/Thomasdezeeuw/a10/commit/ab5ae276e0ca70bf960fcc1d9fa03adce778f729, https://github.com/Thomasdezeeuw/a10/commit/f423cd569aaf18e77e5e392dbf5054b3a35c6145, https://github.com/Thomasdezeeuw/a10/commit/5d489afdde0a44fb9585970f6d386e42aace87ae, https://github.com/Thomasdezeeuw/a10/commit/1eea10736d305c62edccffc53066a2ed228da6fb, https://github.com/Thomasdezeeuw/a10/commit/632fc39963e02f396f26882abf8ca0eb33660ae8, https://github.com/Thomasdezeeuw/a10/commit/5a8022f6f2d4f6d48a4080987bf9a4af517108ef, https://github.com/Thomasdezeeuw/a10/commit/10a66cbd7fb40d3dcc6deac2dae2d96e0a0605e2, https://github.com/Thomasdezeeuw/a10/commit/518dd0901cd80d8f11c96a6aa50a5ea73239ad5e, https://github.com/Thomasdezeeuw/a10/commit/b6ecb740e9eab2027ffb8d70a76d2285b7b42f83, https://github.com/Thomasdezeeuw/a10/commit/43d4fe1d085c6a5d1eb26044437ae0b99e74e68b, https://github.com/Thomasdezeeuw/a10/commit/0763f2c3244956d183a86f3656be28e8899a683c, https://github.com/Thomasdezeeuw/a10/commit/9f58db14578ef8d8fee2c419417b369d772e2249, https://github.com/Thomasdezeeuw/a10/commit/b7f2b7fe737c9c5aeee0da2c388497aab9388b2a, https://github.com/Thomasdezeeuw/a10/commit/c762ea2fced692e3d8b00285de0b720b68a53409.
