Server state is any state associated with the server as a whole that individual sessions might be interested in. That includes configuration info, address space etc.

Fields

application_uri: UAString

The application URI

product_uri: UAString

The product URI

application_name: LocalizedText

The application name

base_endpoint: String

The protocol, hostname and port formatted as a url, but less the path

start_time: DateTime

The time the server started

namespaces: Vec<String>

The list of namespaces

servers: Vec<String>

The list of servers (by urn)

endpoints: Vec<Endpoint>

config: Arc<Mutex<ServerConfig>>

Server configuration

certificate_store: Arc<Mutex<CertificateStore>>

Certificate store for certs

server_certificate: Option<X509>

Server public certificate read from config location or null if there is none

server_pkey: Option<PKey>

Server private key pair

address_space: Arc<Mutex<AddressSpace>>

The address space

last_subscription_id: UInt32

The next subscription id - subscriptions are shared across the whole server. Initial value is a random u32.

max_subscriptions: usize

Maximum number of subscriptions per session, 0 means no limit (danger)

min_publishing_interval: Duration

Minimum publishing interval

max_keep_alive_count: UInt32

Maxmimum keep alive count

abort: bool

Sets the abort flag that terminates the associated server

diagnostics: ServerDiagnostics

Diagnostic information
