Enum CacheClass 

pub enum CacheClass {
    Bucket {
        margin: usize,
    },
    Entity,
    Mutable,
}

How the trailing edge of an Index mutates over time. Drives the series cache: bucketed indexes have a small fixed volatile tail, entity indexes derive their stable count from a height→first-index mapping, and mutable addr indexes have no immutable region (entries change retroactively).

Variants

Bucket

Append-only with margin trailing entries volatile per ≥6-block reorg.

Fields

margin: usize

Entity

Append-only entity index (one number per tx / input / output / typed addr). Stable count must be looked up via the indexer’s first_X_index[tip - 6] mapping.

Mutable

Retroactively mutable: no immutable region (FundedAddrIndex, EmptyAddrIndex).

Trait Implementations

impl Clone for CacheClass

fn clone(&self) -> CacheClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CacheClass

impl Debug for CacheClass

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

Formats the value using the given formatter.

impl Eq for CacheClass

impl PartialEq for CacheClass

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