Struct posix_mq::Queue

pub struct Queue { /* fields omitted */ }

Represents an open queue descriptor to a POSIX message queue. This carries information about the queue's limitations (i.e. maximum message size and maximum message count).

Methods

impl Queue

fn create(name: Name, max_pending: i64, max_size: i64) -> Result<Queue, Error>

Creates a new queue and fails if it already exists. By default the queue will be read/writable by the current user with no access for other users. Linux users can change this setting themselves by modifying the queue file in /dev/mqueue.

fn open(name: Name) -> Result<Queue, Error>

Opens an existing queue.

fn open_or_create(name: Name) -> Result<Queue, Error>

Opens an existing queue or creates a new queue with the OS default settings.

fn delete(self) -> Result<(), Error>

Delete a message queue from the system. This method will make the queue unavailable for other processes, too!

fn send(&self, msg: &Message) -> Result<(), Error>

fn receive(&self) -> Result<Message, Error>

fn max_pending(&self) -> i64

fn max_size(&self) -> usize
