Struct QueueState 

pub struct QueueState { /* private fields */ }

Validated queue configuration and lifecycle snapshot.

Implementations

impl QueueState

pub const fn unconfigured(max_size: QueueSize, epoch: QueueEpoch) -> Self

Construct an unconfigured queue state.

pub const fn new( max_size: QueueSize, size: Option<QueueSize>, ready: bool, epoch: QueueEpoch, ) -> Result<Self, QueueConfigError>

Construct and validate a queue-state snapshot.

pub const fn max_size(self) -> QueueSize

Maximum queue size supported by the implementation.

pub const fn size(self) -> Option<QueueSize>

Configured queue size, if any.

pub const fn ready(self) -> bool

Whether descriptor publication and consumption are enabled.

pub const fn epoch(self) -> QueueEpoch

Current reset epoch.

Trait Implementations

impl Clone for QueueState

fn clone(&self) -> QueueState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for QueueState

impl Debug for QueueState

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

Formats the value using the given formatter.

impl Eq for QueueState

impl PartialEq for QueueState

fn eq(&self, other: &QueueState) -> 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.
