Struct PoolConfig 

pub struct PoolConfig {
    pub max_connections: u32,
    pub acquire_timeout: Duration,
}

Connection-pool bounds. Callers that hold background tasks open against this store rely on acquire_timeout: when every connection is checked out by a stalled query, it is the only thing that turns “wait forever” into an error the caller can report (INVARIANTS.md GL-18).

Fields

max_connections: u32

The most connections the pool opens at once. Must be positive; defaults to 16.

acquire_timeout: Duration

How long a caller may wait for a free connection before the call fails. Must be positive.

Implementations

impl PoolConfig

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

Rejects a zero max_connections or a zero acquire_timeout.

PostgresStore::connect_with calls this before it opens any connection, so an unsafe bound never reaches the database (INVARIANTS.md 16).
