Struct DatabaseConfig 

pub struct DatabaseConfig {
    pub default: String,
    pub connections: IndexMap<String, ConnectionConfig>,
}

Database configuration. Mirrors Laravel’s config/database.php:

• A default connection name (referenced by models, query builder, migrator).
• A map of named connections — each with its own URL, pool size, optional read replicas.

The default from_env() impl auto-builds a single default connection from DATABASE_URL + DB_POOL. Apps wanting multiple connections set:

DB_CONNECTIONS=default,replica,analytics
DATABASE_URL=postgres://...                 # the "default" connection
DB_REPLICA_URL=postgres://replica/...
DB_ANALYTICS_URL=postgres://analytics/...
DB_DEFAULT=default

Fields

default: String

connections: IndexMap<String, ConnectionConfig>
