Struct Config 

pub struct Config {
    pub path: String,
    pub migrations: Option<String>,
    pub busy_timeout: u64,
    pub cache_size: i64,
    pub mmap_size: u64,
    pub journal_mode: JournalMode,
    pub synchronous: SynchronousMode,
    pub foreign_keys: bool,
    pub temp_store: TempStore,
    pub pool: Option<PoolConfig>,
}

Database configuration with sensible defaults for SQLite/libsql.

All fields are optional when deserializing from YAML. Defaults produce a WAL-mode database at data/app.db with foreign keys enabled.

If migrations is set, SQL migrations from that directory are applied automatically on connect.

Fields

path: String

Database file path.

migrations: Option<String>

Migration directory. If set, migrations run on connect.

busy_timeout: u64

Busy timeout in milliseconds.

cache_size: i64

Cache size in KB (applied as PRAGMA cache_size = -N).

mmap_size: u64

Memory-mapped I/O size in bytes.

journal_mode: JournalMode

WAL journal mode.

synchronous: SynchronousMode

Synchronous mode.

foreign_keys: bool

Foreign key enforcement.

temp_store: TempStore

Temp store location.

pool: Option<PoolConfig>

Optional pool configuration for multi-database sharding. When set, DatabasePool::new can be used to manage shard databases that share this config’s PRAGMAs and migrations.
