[dependabot-preview]

Updates the requirements on mio to permit the latest version.

Changelog

Sourced from mio's changelog.

0.7.6

Added

• net feature, replaces tcp, udp and uds features (tokio-rs/mio@a301ba5).
• os-ext feature, replaces os-util and pipe features (tokio-rs/mio@f5017fa).
• Added keepalive support to TcpSocket (tokio-rs/mio@290c43a).
• TcpSocket::set_{send, recv}_buffer_size (tokio-rs/mio@40c4af7).
• TcpSocket::get_linger (tokio-rs/mio@13e82ce).
• Implement IntoRawFd for TcpSocket (tokio-rs/mio@50548ed).

Deprecated

• The tcp, udp and uds features, replaced by a new net feature. (tokio-rs/mio@a301ba5).
• The extra-docs feature, now enabled by default. (tokio-rs/mio@25731e8).
• The os-util and pipe features, replaced by a new os-ext feature. (tokio-rs/mio@f5017fa).

Fixes

• Incorrect assumption of the layout of std::net::SocketAddr. Previously Mio would assume that SocketAddrV{4,6} had the same layout as libc::sockaddr_in(6), however this is not guaranteed by the standard library. (tokio-rs/mio@152e075).
• Also bumped the miow dependency to version 0.3.6 to solve the same problem as above.

0.7.5

Added

• TcpSocket::get_localaddr() retrieves local address (tokio-rs/mio@b41a022).
• TcpSocket::set_reuseport() & TcpSocket::get_reuseport() configures and reads SO_REUSEPORT (tokio-rs/mio@183bbe4).
• unix:pipe() a wrapper around pipe(2) sys call (tokio-rs/mio@2b7c096).
• Add a check that a single Waker is active per Poll instance (only in debug mode) (tokio-rs/mio@f4874f2).
• Added Interest:remove() (tokio-rs/mio@b8639c3).
