Struct gio::UnixSocketAddress[−][src]

pub struct UnixSocketAddress(_);

Expand description

Support for UNIX-domain (also known as local) sockets.

UNIX domain sockets are generally visible in the filesystem. However, some systems support abstract socket names which are not visible in the filesystem and not affected by the filesystem permissions, visibility, etc. Currently this is only supported under Linux. If you attempt to use abstract sockets on other systems, function calls may return IOErrorEnum::NotSupported errors. You can use abstract_names_supported() to see if abstract names are supported.

Note that <gio/gunixsocketaddress.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Implementations

impl UnixSocketAddress

pub fn new(path: &Path) -> UnixSocketAddress

Creates a new UnixSocketAddress for path.

To create abstract socket addresses, on systems that support that, use g_unix_socket_address_new_abstract().

`path`

the socket path

Returns

a new UnixSocketAddress

pub fn with_type(address_type: UnixSocketAddressPath<'_>) -> Self

Creates a new UnixSocketAddress of type type_ with name path.

If type_ is UnixSocketAddressType::Path, this is equivalent to calling new().

If type_ is UnixSocketAddressType::Anonymous, path and path_len will be ignored.

If path_type is UnixSocketAddressType::Abstract, then path_len bytes of path will be copied to the socket’s path, and only those bytes will be considered part of the name. (If path_len is -1, then path is assumed to be NUL-terminated.) For example, if path was “test”, then calling SocketAddressExt::native_size() on the returned socket would return 7 (2 bytes of overhead, 1 byte for the abstract-socket indicator byte, and 4 bytes for the name “test”).

If path_type is UnixSocketAddressType::AbstractPadded, then path_len bytes of path will be copied to the socket’s path, the rest of the path will be padded with 0 bytes, and the entire zero-padded buffer will be considered the name. (As above, if path_len is -1, then path is assumed to be NUL-terminated.) In this case, SocketAddressExt::native_size() will always return the full size of a struct sockaddr_un, although UnixSocketAddressExt::path_len() will still return just the length of path.

UnixSocketAddressType::Abstract is preferred over UnixSocketAddressType::AbstractPadded for new programs. Of course, when connecting to a server created by another process, you must use the appropriate type corresponding to how that process created its listening socket.

`path`

the name

`type_`

a UnixSocketAddressType

Returns

a new UnixSocketAddress
