Struct PoolStats 

pub struct PoolStats {
    pub reuses: u64,
    pub opens: u64,
    pub expirations: u64,
    pub in_use: usize,
}

Statistics about pool usage.

Fields

reuses: u64

Number of connection reuses.

opens: u64

Number of new connections opened.

expirations: u64

Number of connections closed due to expiration.

in_use: usize

Total number of connection checkouts since the pool was created (or since the last SqlitePool::reset_stats call).

This counter is cumulative: it is incremented on every SqlitePool::get but never decremented, because SqliteConnection holds no handle back to the pool’s stats to decrement on drop. Read it as total checkouts, not as the number of connections currently checked out.
