Fields

data_dir: PathBuf

default_ttl_secs: Option<u64>

gc_interval_secs: u64

memtable_size_mb: usize

max_frozen_memtables: usize

block_size: usize

zstd_level: i32

flush_interval_ms: u64

time_bucket_secs: u64

index_memory_budget_mb: usize

block_cache_capacity_mb: usize

bloom_bits_per_key: usize

wal_segment_size_mb: u64

compaction_threshold: usize

create_if_missing: bool

wal_sync_mode: SyncMode

Controls how the WAL is synchronised to stable storage. Always guarantees every acknowledged write is on disk before returning. IntervalMs(n) batches fsync calls up to every n milliseconds for higher throughput at the cost of potentially losing the most recent writes on power failure.

auto_background: bool

When true, the engine automatically spawns a background task that periodically flushes the memtable, compacts SSTables, garbage-collects expired data, and syncs the WAL (for IntervalMs mode). Set to false in tests that want full control over when flush/compact/GC occur.

Implementations

impl Config

pub fn validate(&self) -> Result<()>

Validate all configuration fields and return an error if any value is out of range or would cause runtime panics (e.g. division by zero in the time-bucket index). Called by Engine::open.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
