pub struct SocketListener {
    fd: SystemListener,
    drop_path: Option<Box<dyn Any>>,
}

Unix domain socket listener for accepting incoming connections.

Fields

fd: SystemListener

drop_path: Option<Box<dyn Any>>

Implementations

impl SocketListener

pub fn new<P: AsRef<Path>>(path: P, unlink: bool) -> Result<Self>

Create a unix domain socket listener.

Return:

• • the new SocketListener object on success.
• • SocketError: failed to create listener socket.

pub fn take_resources_for_parent(&mut self) -> Option<Box<dyn Any>>

Take and return the resources that the parent process needs to keep alive as long as the child process lives, in case of incoming fork.

Trait Implementations

impl AsRawDescriptor for SocketListener

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl Listener for SocketListener

fn accept(&mut self) -> Result<Option<Connection<FrontendReq>>>

Accept an incoming connection.

Return:

• • Some(SystemListener): new SystemListener object if new incoming connection is available.
• • None: no incoming connection available.
• • SocketError: errors from accept().

fn set_nonblocking(&self, block: bool) -> Result<()>

Change blocking status on the listener.

Return:

• • () on success.
• • SocketError: failure from set_nonblocking().
