Struct mtbl::WriterOptions
[−]
[src]
pub struct WriterOptions {
pub compression: Option<CompressionType>,
pub block_size: Option<usize>,
pub block_restart_interval: Option<usize>,
}Options for writing an MTBL file.
Examples
let writer = WriterOptions::new() .compression(CompressionType::MTBL_COMPRESSION_SNAPPY) .create_from_path("/tmp/f.mtbl");Run
Fields
compression: Option<CompressionType>
What compression type to use. Default is to use zlib.
block_size: Option<usize>
What block size to use, in bytes. Default is 8 KiB.
block_restart_interval: Option<usize>
How often, in keys, to restart intra-block key prefix compression. Default is every 16 keys.
Methods
impl WriterOptions[src]
fn new() -> WriterOptions[−]
