Struct EngramRowReader 

pub struct EngramRowReader { /* private fields */ }

Row reads from the engram tables. The tables are ~30 GiB each and a token touches 24 rows per table, so nothing is cached: every call is ids.len() positional reads of one block.

Implementations

impl EngramRowReader

pub fn new(files: Arc<ShardFiles>) -> Result<Self>

pub fn tables(&self) -> &[EngramTable]

pub fn table(&self, layer: usize) -> Option<&EngramTable>

pub fn read_rows(&self, layer: usize, ids: &[u64], dst: &mut [u8]) -> Result<()>

Read rows ids of layer layer’s table into dst (ids.len() * row_bytes bytes, in ids order).
