Struct DatabaseRuntimeConfig 

pub struct DatabaseRuntimeConfig {
    pub url: Option<String>,
    pub pool_min: usize,
    pub pool_max: usize,
    pub connect_timeout_ms: u64,
    pub idle_timeout_ms: u64,
    pub ssl_mode: String,
}

Database connection pool runtime configuration.

The [database] section in fraiseql.toml is optional. When absent, connection parameters fall back to the DATABASE_URL environment variable or the --database CLI flag.

Supports ${VAR} environment variable interpolation in the url field:

[database]
url      = "${DATABASE_URL}"
pool_min = 2
pool_max = 20
ssl_mode = "prefer"

Fields

url: Option<String>

Database connection URL. Supports ${VAR} interpolation.

If not set here, the runtime falls back to the DATABASE_URL environment variable or the --database CLI flag.

pool_min: usize

Minimum connection pool size. Default: 2.

pool_max: usize

Maximum connection pool size. Default: 20.

connect_timeout_ms: u64

Connection acquisition timeout in milliseconds. Default: 5 000 (5 s).

idle_timeout_ms: u64

Idle connection lifetime in milliseconds. Default: 600 000 (10 min).

ssl_mode: String

PostgreSQL SSL mode: "disable", "allow", "prefer", or "require". Default: "prefer".
