Member Data Documentation

index_at_end

bool zarr::shard::Placement::index_at_end = true

index_location: end (default, index is the trailing index_size bytes) or start (index is the leading index_size bytes).

index_size

std::uint64_t zarr::shard::Placement::index_size = 0

Encoded byte size of the shard index; fetch this many bytes at the index location (a suffix range when index_at_end, else a prefix range).
