Struct ReadOptions 

pub struct ReadOptions {
    pub snapshot: Option<u64>,
    pub fill_cache: bool,
    pub verify_checksums: bool,
    pub readahead_size: usize,
    pub total_order_seek: bool,
    pub pin_data: bool,
}

Options for read operations.

Fields

snapshot: Option<u64>

If set, reads will use this snapshot sequence number.

fill_cache: bool

Whether to fill the block cache for this read. Default: true.

verify_checksums: bool

Whether to verify checksums on reads. Default: false.

readahead_size: usize

Readahead size hint in bytes for sequential iteration. 0 = auto. Default: 0. RocksDB equivalent: readahead_size.

total_order_seek: bool

If true, ignore prefix bloom filters and do a total order seek. Default: false. RocksDB equivalent: total_order_seek.

pin_data: bool

If true, pin data blocks in memory during iteration. Default: false. RocksDB equivalent: pin_data.
