Struct UnixStream 

pub struct UnixStream { /* private fields */ }

Owned non-blocking Unix stream descriptor.

Implementations

impl UnixStream

pub fn fd(&self) -> &Fd

Access the underlying descriptor for reactor registration and raw byte helpers.

impl UnixStream

pub fn peer_cred(&self) -> Result<Option<PeerCred>, CoreError>

Return peer credentials when the platform supports SO_PEERCRED.

Errors

• EBADF: The file descriptor is invalid.
• ENOPROTOOPT: SO_PEERCRED is not supported by the socket.

Example

let creds = stream.peer_cred().unwrap();
if let Some(c) = creds {
    println!("Peer UID: {}", c.uid);
}

pub fn check_connect_error(&self) -> Result<Option<i32>, CoreError>

Return the pending SO_ERROR connect status.

Ok(None) means no pending socket error was reported. Ok(Some(code)) returns the raw connect error without making a policy decision.

Errors

• EBADF: The file descriptor is invalid.

pub fn finish_connect(self) -> Result<Self, CoreError>

Finish a non-blocking connect after the socket becomes writable.

Returns the stream when SO_ERROR is clear; otherwise returns the raw socket error as CoreError.

Errors

Returns the same errors as Self::check_connect_error, or the pending connection error itself.
