Struct pagecache::Config

pub struct Config { /* fields omitted */ }

Top-level configuration for the system.

Examples

let _config = sled::Config::default()
    .path("/path/to/data".to_owned())
    .cache_capacity(10_000_000_000)
    .use_compression(true)
    .flush_every_ms(Some(1000))
    .snapshot_after_ops(100_000);

Read-only mode let _config = sled::Config::default() .path("/path/to/data".to_owned()) .read_only(true);
