Enum SizeClass 

pub enum SizeClass {
    Small = 0,
    Medium = 1,
    Large = 2,
    Huge = 3,
}

Buffer size classes

Variants

Small = 0

Small buffers (<= 4KB) - for headers, small messages

Medium = 1

Medium buffers (<= 64KB) - for typical messages

Large = 2

Large buffers (<= 1MB) - for batch operations

Huge = 3

Huge buffers (> 1MB) - direct allocation

Implementations

impl SizeClass

pub const fn size(&self) -> usize

Get the buffer size for this class

pub fn for_size(size: usize) -> Self

Determine size class for a given size

Trait Implementations

impl Clone for SizeClass

fn clone(&self) -> SizeClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SizeClass

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

Formats the value using the given formatter.

impl PartialEq for SizeClass

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