Struct cap_std::os::unix::net::UnixStream

pub struct UnixStream { /* fields omitted */ }

A Unix stream socket.

This corresponds to std::os::unix::net::UnixStream.

Note that this UnixStream has no connect method. To create a UnixStream, you must first obtain a Dir containing the path, and then call Dir::connect_unix_stream.

Implementations

impl UnixStream

pub fn from_std(std: UnixStream, _: AmbientAuthority) -> Self

Constructs a new instance of Self from the given std::os::unix::net::UnixStream.

Ambient Authority

std::os::unix::net::UnixStream is not sandboxed and may access any address that the host process has access to.
