Struct ConnectHandlers 

#[non_exhaustive]
pub struct ConnectHandlers {
    pub connection_listener: Option<ConnectionListener>,
    pub connection_event_inbox_capacity: usize,
    pub error_handler: Option<QwpWsErrorHandler>,
    pub error_inbox_capacity: usize,
}

Connection pool for QWP/WebSocket ingestion and egress.

Construct with QuestDb::connect. Share the pool across threads — its internal state is Mutex-guarded so QuestDb::borrow_sender / QuestDb::reap_idle / Drop-driven returns are safe to interleave.

Each borrow (BorrowedSender / the internal direct sender) is not Send — it belongs to the thread that borrowed it. To ingest in parallel, borrow one sender per worker thread from the same QuestDb. Optional per-pool event handlers for QuestDb::connect_with_handlers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

connection_listener: Option<ConnectionListener>

Connection lifecycle listener; see QuestDb::connect_with_listener.

connection_event_inbox_capacity: usize

Listener inbox capacity; 0 selects the default (64).

error_handler: Option<QwpWsErrorHandler>

Server-rejection handler; without one every rejection is logged.

error_inbox_capacity: usize

Handler inbox capacity; 0 selects the default (64).
