Expand description

Options to tweak compression.

Fields§

§dict_size_log2: u32

The base 2 log of the dictionary size.

§compression_level: CompressionLevel

The level of compression.

§table_update_rate: TableUpdateRate

The table update rate.

It can be overwritten by specifying table_update_interval.

§max_helper_threads: i32

The maximum number of helper threads to use.

§compression_flags: Option<CompressionFlag>

Flags to pass to the compression.

Currently unimplemented.

§num_seed_bytes: Option<u32>

Number of seed bytes to load.

§p_seed_bytes: Option<Vec<u8>>

A vector of seed bytes to load.

§table_update_interval: Option<TableUpdateInterval>

The table update interval.
