Enum SizeBucket 

pub enum SizeBucket {
    Tiny,
    Small,
    Medium,
    Large,
    Huge,
}

Size bucket for stratified pooling.

Provides predefined size classes for efficient multi-size pooling. Allocations are rounded up to the smallest bucket that fits.

Variants

Tiny

Tiny buffers (256 bytes) - metadata, small messages.

Small

Small buffers (1 KB) - typical message payloads.

Medium

Medium buffers (4 KB) - page-sized allocations.

Large

Large buffers (16 KB) - batch operations.

Huge

Huge buffers (64 KB) - large transfers.

Implementations

impl SizeBucket

pub const ALL: [SizeBucket; 5]

All bucket variants in order from smallest to largest.

pub fn size(&self) -> usize

Get the size in bytes for this bucket.

pub fn for_size(requested: usize) -> Self

Find the smallest bucket that fits the requested size.

Returns Huge for any size larger than 16KB.

pub fn upgrade(&self) -> Self

Get the next larger bucket, or self if already at largest.

pub fn downgrade(&self) -> Self

Get the next smaller bucket, or self if already at smallest.

Trait Implementations

impl Clone for SizeBucket

fn clone(&self) -> SizeBucket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SizeBucket

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

Formats the value using the given formatter.

impl Default for SizeBucket

fn default() -> SizeBucket

Returns the “default value” for a type.

impl Display for SizeBucket

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

Formats the value using the given formatter.

impl Hash for SizeBucket

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 SizeBucket

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