Enum Tier 

#[repr(u8)]
pub enum Tier {
    Tier0 = 0,
    Tier1 = 1,
    Tier2 = 2,
    Tier3 = 3,
}

Storage tier for a block.

Tiers form a hierarchy from hot (high fidelity, fast access) to evicted (metadata-only, zero payload bytes).

Variants

Tier0 = 0

Evicted: compressed to zero bits, only metadata remains.

Tier1 = 1

Hot: 8-bit quantization, full fidelity.

Tier2 = 2

Warm: 7-bit quantization.

Tier3 = 3

Cold: 3-bit quantization.

Trait Implementations

impl Clone for Tier

fn clone(&self) -> Tier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tier

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

Formats the value using the given formatter.

impl Hash for Tier

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 Tier

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