SyncColdRead

Struct SyncColdRead

pub struct SyncColdRead;

Expand description

The default reader: one ordered pread per record.

Trait Implementations§

impl ColdBatchReader for SyncColdRead

fn read_batch(&mut self, reads: &[ColdRead]) -> Result<(Vec<Vec<u8>>, u64)>

Fetch each reads[i]’s raw image (vref.disk_len() bytes at vref.offset, unverified — the store runs verify_image + decode on completion). Returns the images plus the number of kernel submissions made (1 for the sync loop, ceil(n / ring entries) for a ring).
