Struct PoolConfig 

pub struct PoolConfig {
    pub max_connections: Option<u32>,
    pub min_connections: Option<u32>,
    pub acquire_timeout_secs: Option<u64>,
    pub idle_timeout_secs: Option<u64>,
    pub max_lifetime_secs: Option<u64>,
}

Declarative pool configuration.

All fields are optional; unset fields use SQLx defaults. Can be converted into a PoolBuilder via PoolConfig::into_builder.

Environment variables

PoolConfig::from_env() reads:

• DATABASE_MAX_CONNECTIONS
• DATABASE_MIN_CONNECTIONS
• DATABASE_ACQUIRE_TIMEOUT_SECS
• DATABASE_IDLE_TIMEOUT_SECS
• DATABASE_MAX_LIFETIME_SECS

Fields

max_connections: Option<u32>

min_connections: Option<u32>

acquire_timeout_secs: Option<u64>

idle_timeout_secs: Option<u64>

max_lifetime_secs: Option<u64>
