Fields

ocpp_listen: Option<SocketAddr>

Plain (unencrypted) listener for charging stations; none disables it. Env: OCPP_LISTEN.

ocpp_tls_listen: Option<SocketAddr>

TLS listener for charging stations (Security Profiles 2 and 3). Env: OCPP_TLS_LISTEN.

tls: Option<TlsSettings>

Env: OCPP_TLS_CERT/OCPP_TLS_KEY (+ optional OCPP_TLS_CERT2/OCPP_TLS_KEY2), OCPP_TLS_CLIENT_CA, OCPP_TLS_CIPHERS.

cso_name: Option<String>

CSO name expected in the O RDN of station certificates (A00.FR.404). Env: OCPP_CSO_NAME.

max_connections: usize

Maximum concurrent station connections per listener. Env: OCPP_MAX_CONNECTIONS.

api_listen: SocketAddr

Listener for the internal HTTP API. Env: API_LISTEN.

database_url: String

Env: DATABASE_URL.

database_max_connections: u32

Env: DATABASE_MAX_CONNECTIONS.

node_id: String

Identifies this instance in the charging_stations.connected_node column. Env: NODE_ID.

versions: Vec<OcppVersion>

OCPP versions offered to stations. Env: OCPP_VERSIONS (e.g. 1.6,2.0.1,2.1).

heartbeat_interval: Duration

Heartbeat interval returned in BootNotification responses. Env: HEARTBEAT_INTERVAL_SECS.

call_timeout: Duration

Timeout for CSMS-initiated calls. Env: CALL_TIMEOUT_SECS.

ping_interval: Duration

Server-side WebSocket ping interval when the link is idle; 0 disables. Env: PING_INTERVAL_SECS.

max_message_size: usize

Env: MAX_MESSAGE_SIZE (bytes).

ws_deflate: bool

RFC 7692 permessage-deflate. Env: WS_DEFLATE.

ws_force_client_no_context_takeover: bool

Impose client_no_context_takeover to save memory. Env: WS_FORCE_CLIENT_NO_CONTEXT_TAKEOVER.

require_password: bool

Reject stations that have no password configured (Security Profile ≥ 1 everywhere). Env: OCPP_REQUIRE_PASSWORD.

authorize_unknown_tokens: bool

Accept id tokens that are not in the database. Env: AUTHORIZE_UNKNOWN_TOKENS.

api_token: Option<String>

Bearer token required by the HTTP API, if set. Env: API_TOKEN.

command_queue_size: usize

Max queued commands per station connection. Env: COMMAND_QUEUE_SIZE.

auth_concurrency: usize

Max concurrent password verifications (argon2 is memory-hard). Env: AUTH_CONCURRENCY.

nominal_voltage: f64

Nominal phase voltage used to convert A ↔ W in composite schedules. Env: NOMINAL_VOLTAGE.

ev_charging_needs: bool

Answer ISO 15118 NotifyEVChargingNeeds with a TxProfile (K15–K19). Env: SMART_CHARGING_EV_NEEDS.

allow_bidirectional: bool

Accept bidirectional energy transfer modes requested by EVs (OCPP 2.1). Env: ALLOW_BIDIRECTIONAL.

reservation_sweep_interval: Duration

How often expired reservations are closed. Env: RESERVATION_SWEEP_SECS.

default_timezone: String

Time zone of stations without their own (tariff conditions use local time). Env: DEFAULT_TIMEZONE.

zoneinfo_dir: PathBuf

Directory of the IANA time zone database. Env: TZDIR.
