Enum StackSizeClass 

pub enum StackSizeClass {
    Small = 4_096,
    Medium = 16_384,
    Large = 65_536,
    ExtraLarge = 262_144,
}

Stack size classes for the pool allocator.

Different threads may need different stack sizes, so we provide several size classes to minimize memory waste.

Variants

Small = 4_096

Small stack: 4 KiB

Medium = 16_384

Medium stack: 16 KiB

Large = 65_536

Large stack: 64 KiB

ExtraLarge = 262_144

Extra large stack: 256 KiB

Implementations

impl StackSizeClass

pub fn size(self) -> usize

Get the size in bytes for this stack class.

pub fn for_size(requested_size: usize) -> Option<Self>

Choose the appropriate size class for a requested stack size.

Arguments

• requested_size - The minimum stack size required

Returns

The smallest size class that can accommodate the requested size.

Trait Implementations

impl Clone for StackSizeClass

fn clone(&self) -> StackSizeClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StackSizeClass

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

Formats the value using the given formatter.

impl PartialEq for StackSizeClass

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