v0.3.1

  • BREAKING: IoMutSlice::new was made private, it was never meant to be public. #200.
  • Added AsyncFd::set_socket_option2 and AsyncFd::socket_option2, which provide a type safe interface around AsyncFd::(set_)socket_option #201.
  • The io module documentation was expanded and improved #202.

v0.3.0

  • Complete rewrite of the internals to make it easier to port.
  • The methods on Config are now implementation specific.
  • Removed the D: Descriptor generic parameter from AsyncFd, this is now handled internally.
  • The Descriptor trait, File and Direct enums are now replaced by fd::Kind.
  • Futures that create AsyncFd, such as net::Socket and fs::OpenOptions now have a kind method that sets the fd kind.
  • 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. It's now implemented for SocketAddr, SocketAddrV4, SocketAddrV6 and unix::net::addr::SocketAddr.
  • 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 Message type as type for message data, instead of u32 (though Message is also u32).
  • process::ReceiveSignals is now a proper AsyncIter.
  • More implementations for Buf were added for Cow<'static, [u8]>, Cow<'static, str>, Box<str>, Arc<[u8]> and Arc<str>.
  • Ring::submission_queue has been renamed to Ring::sq, because it's shorter.
  • All types from external crates have been removed from the public API (that was mainly libc).
    • Signals methods now accept SignalSet instead of libc::sigset_t.
    • Signals and ReceiveSignals now returns SignalInfo instead of libc::signalfd_siginfo.
    • process::wait and process:wait_on now accepts WaitOption instead of c_int.
    • process::wait and process:wait_on now returns WaitInfo instead of libc::siginfo_t.
    • process::Signals now accepts SignalSet and Signal in created of libc::sigset_t.
    • process::Signals::receive_signals returns SignalInfo instead of libc::signalfd_siginfo.
    • poll::multishot_poll and poll::oneshot_poll now accepts Interest instead of c_int.
    • AsyncFd::advise now accepts fs::AdviseFlag instead of c_int.
    • AsyncFd::allocate now accepts fs::AllocateFlag instead of c_int.
    • AsyncFd::multishot_accept4 now accepts net::AcceptFlag instead of c_int.
    • AsyncFd::multishot_recv now accepts net::RecvFlag instead of c_int.
    • AsyncFd::recv and related functions now accepts RecvFlag instead of c_int.
    • AsyncFd::send and related functions now accepts SendFlag instead of c_int.
    • AsyncFd::accept4 now accepts AcceptFlag instead of c_int.
    • AsyncFd::splice and related function now accepts SpliceFlag instead of c_int.
    • AsyncFd::set_socket_option and AsyncFd::socket_option now accepts net::Level and net::Opt instead of c_int.
    • net::socket now accepts Domain, Type and Protocol instead of c_ints.
    • mem::advise now accepts AdviseFlag instead of c_int.
  • AsyncFd also gained a number of new methods:
    • AsyncFd::kind returns the fd::Kind.
    • AsyncFd::multishot_read multishot read, similar to multishot recv.
    • AsyncFd::send_all_zc send all bytes using zero-copy I/O.
    • AsyncFd::send_all_vectored_zc send all using zero-copy vectored I/O.
    • AsyncFd::bind the bind(2) system call.
    • AsyncFd::listen the listen(2) system call.
    • AsyncFd::connect the connect(2) system call.
  • The buffer traits have some new methods:
    • Buf::len returns the length.
    • Buf::is_empty returns true if the buffer is empty.
    • Buf::as_slice returns the buffer as slices.
    • BufMut::extend_from_slice and BufMutSlice::extend_from_slice extends the buffer with a slice.
    • BufSlice::total_len returns the total length.
  • New pipe module that wraps the pipe(2) system call.
  • The msg module was redesigned. It nows uses a Listen and Sender.
    • msg_listener was renamed to msg::listener.
    • MsgListener was renamed to msg::Listener.
    • send_msg and try_send_msg were merged into msg::Listener.
    • MsgToken was removed, it's now part of msg::Sender.
  • Various types were renamed:
    • CancelOp to CancelOperation
    • poll::PollEvent to poll::Event.
    • process::ToSignalsDirect to process::ToDirect.

v0.2.2

v0.2.1

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.

v0.1.9

v0.1.8

v0.1.7

v0.1.6

v0.1.5

v0.1.4

  • Fixed dropping of ReceiveSignals, it now properly cancels the receiving of process signals and ensure the kernel doesn't write into deallocated memory #81.

v0.1.3

  • Added ReceiveSignals, a type that combines Signals and signals::Receive to not have to deal with lifetime of the fd #79.

v0.1.2

  • Added support for user space messaging, see SubmissionQueue::msg_listener and SubmissionQueue::(try_)send_msg #76.
  • Returns more accurate io::ErrorKinds for certain errors when nightly feature is enabled #77.

v0.1.1

  • Don't leak SubmissionQueue in Std{in,out,err} types #72.
  • Implement fmt::Debug for Std{in,out,err} and improve the implemtation for AsyncFd and SubmissionQueue #73.

v0.1.0

Initial release.
