TableState

Struct TableState 

Source
pub struct TableState {
    pub version: u64,
    pub table_meta: TableMeta,
    pub segments: HashMap<String, SegmentMeta>,
    pub table_coverage: Option<TableCoveragePointer>,
}
Expand description

In-memory view of table metadata and live segments, reconstructed from the log.

Invariant:

  • version matches the CURRENT pointer.
  • table_meta and segments are the result of applying all commits from version 1 through version in order.

Fields§

§version: u64

Latest committed version recorded in CURRENT.

§table_meta: TableMeta

Table-level metadata reconstructed from the log.

§segments: HashMap<String, SegmentMeta>

Current live segments keyed by canonical table-relative path.

§table_coverage: Option<TableCoveragePointer>

Optional pointer to the latest table coverage metadata.

Implementations§

Source§

impl TableState

Source

pub fn segments_sorted_by_index( &self, ) -> Result<Vec<&SegmentMeta>, IndexValueError>

Return live segments sorted deterministically by ordered-index bounds.

Ordering is by index_min, then index_max, and finally path as a stable tie-breaker.
