Struct Fds 

pub struct Fds { /* private fields */ }

Available on Unix only.

Container for open file descriptors and their associated bind addresses.

Implementations

impl Fds

pub fn new() -> Self

pub fn add(&mut self, bind: String, fd: RawFd)

pub fn get(&self, bind: &str) -> Option<&RawFd>

pub fn is_empty(&self) -> bool

pub fn serialize(&self) -> (Vec<String>, Vec<RawFd>)

pub fn deserialize(&mut self, binds: Vec<String>, fds: Vec<RawFd>)

pub fn send_to_sock<P>(&self, path: &P) -> Result<usize, Error>

where P: ?Sized + NixPath + Display,

pub fn get_from_sock<P>(&mut self, path: &P) -> Result<(), Error>

where P: ?Sized + NixPath + Display,

pub fn close_unclaimed(&mut self, keep: &HashSet<String>) -> Vec<String>

Close and remove inherited listening fds whose bind addresses are absent from keep.

An unclaimed SO_REUSEPORT socket remains active without an acceptor and can black-hole connections. Removing it also prevents it from being transferred to the next process. Returns the addresses removed from the table.
