Enum IndexState 

pub enum IndexState {
    Building {
        cursor: u64,
    },
    Ready,
    Dropping {
        cursor: u64,
    },
}

Lifecycle of an index. Records covered by the entries: Building{cursor} covers ordinals < cursor, Ready covers all, and Dropping{cursor} covers ordinals ≥ cursor.

Variants

Building

Backfill has covered records below cursor.

Fields

cursor: u64

First record ordinal not yet backfilled.

Ready

Every record is covered; the planner may use the index.

Dropping

Entries of records below cursor have been removed.

Fields

cursor: u64

First record ordinal whose entries remain.

Implementations

impl IndexState

pub fn covered(self) -> (u64, u64)

Half-open ordinal interval [start, end) of covered records.

pub fn covers(self, ord: u64) -> bool

Whether record ordinal ord is covered.

pub fn label(self) -> &'static str

Wire label (building, ready, dropping).
