Struct ResultSet 

pub struct ResultSet {
    pub(super) slots: Vec<Arc<VolumeSlot>>,
    pub(super) structural: Vec<u64>,
    pub(super) rows: Vec<(u32, EntryId)>,
}

Materialized, sort-ordered result. Pages are O(1) slices; reads stay valid across content mutations and fail with Stale only after a structural change (compaction/rescan).

Fields

slots: Vec<Arc<VolumeSlot>>

structural: Vec<u64>

rows: Vec<(u32, EntryId)>

Implementations

impl ResultSet

pub const fn len(&self) -> usize

Number of rows in the materialized result.

pub const fn is_empty(&self) -> bool

True when the result contains no rows.

pub fn fill_page( &self, offset: usize, count: usize, ) -> Result<(Vec<FmfRow>, Vec<u8>), EngineError>

Builds the shared page representation — 48-byte contract rows plus one string blob, offsets blob-relative — the single implementation behind both the FFI FmfPage and the pipe ResultPage payload (ADR-0018). Blob layout: per row, name bytes then parent bytes, in row order (the canonical layout the golden corpus pins).

Errors

Returns EngineError::Stale if the underlying index changed since this result set was produced (the handle is stale).

pub fn page(&self, offset: usize, count: usize) -> Result<Vec<Row>, EngineError>

Materialize [offset, offset + count) of the result into owned rows.

Errors

Returns EngineError::Stale if any backing volume index changed since this result set was produced (the handle is stale).
