Module handler 

Structs

ConnOpts

Options for a single connection, bundled to keep handle_connection’s argument list short.

Principal

An authenticated connection’s identity. Bound at connect time and consulted on every query by dispatch_query to enforce the user’s role: a readonly principal may only execute read statements.

Enums

AuthOutcome

Result of the connect-time authentication decision.

Functions

authenticate_connect

Pure, exhaustively-testable authentication decision for a CONNECT handshake.

handle_connection

new_rate_limiter

Create a new shared rate limiter.

new_tx_gate

Create a transaction gate for a shared engine.

Type Aliases

AuthRateLimiter

Tracks per-IP authentication failure counts for rate limiting.

TxGate

Gate that serializes wire-protocol statements while an explicit transaction is open on any connection. The connection that runs begin keeps an owned permit until commit, rollback, disconnect, or timeout, preventing other connections from observing or joining uncommitted state.
