Struct Attributes 

pub struct Attributes {
    pub max_msg_len: usize,
    pub capacity: usize,
    pub current_messages: usize,
    pub nonblocking: bool,
    /* private fields */
}

Contains information about the capacities and state of a posix message queue.

Created by PosixMq::attributes().

Fields

max_msg_len: usize

The maximum size of messages that can be stored in the queue.

capacity: usize

The maximum number of messages in the queue.

current_messages: usize

The number of messages currently in the queue at the time the attributes were retrieved.

nonblocking: bool

Whether the descriptor was set to nonblocking mode when the attributes were retrieved.

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attributes

fn fmt(&self, fmtr: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
