Enum QueueTier 

pub enum QueueTier {
    Small,
    Medium,
    Large,
    ExtraLarge,
}

Queue capacity tiers for dynamic queue allocation.

Instead of dynamic resizing (which is complex for GPU memory), we provide predefined tiers that can be selected based on expected load.

Variants

Small

Small queues (256 messages) - low traffic, minimal memory.

Medium

Medium queues (1024 messages) - moderate traffic.

Large

Large queues (4096 messages) - high traffic.

ExtraLarge

Extra large queues (16384 messages) - very high traffic.

Implementations

impl QueueTier

pub fn capacity(&self) -> usize

Get the capacity for this tier.

pub fn for_throughput(messages_per_second: u64, target_headroom_ms: u64) -> Self

Suggest a tier based on expected message rate.

Arguments

• messages_per_second - Expected message throughput
• target_headroom_ms - Desired buffer time in milliseconds

Returns

Recommended tier based on traffic patterns.

pub fn upgrade(&self) -> Self

Get the next tier up (for capacity planning).

pub fn downgrade(&self) -> Self

Get the tier below (for memory optimization).

Trait Implementations

impl Clone for QueueTier

fn clone(&self) -> QueueTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueueTier

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

Formats the value using the given formatter.

impl Default for QueueTier

fn default() -> QueueTier

Returns the “default value” for a type.

impl Hash for QueueTier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for QueueTier

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