Struct opcua_server::builder::ServerBuilder

pub struct ServerBuilder { /* fields omitted */ }

The ServerBuilder is a builder for producing a Server. It is an alternative to constructing a ServerConfig from file or from scratch.

Implementations

impl ServerBuilder

pub fn new() -> Self

pub fn from_config(config: ServerConfig) -> Self

Reads the config in as a starting point

pub fn new_anonymous<T>(application_name: T) -> Self where
    T: Into<String>, 

Creates a simple endpoint that accepts anonymous connections

pub fn new_sample() -> Self

Creates and yields a builder which is configured with the sample server configuration. Use this for testing and similar reasons. Do not rely upon this in production code because it could change.

pub fn server(self) -> Option<Server>

Yields a [Client] from the values set by the builder. If the builder is not in a valid state it will return None.

pub fn config(self) -> ServerConfig

Yields a [ClientConfig] from the values set by the builder.

pub fn is_valid(&self) -> bool

Test if the builder can yield a server with the configuration supplied.

pub fn application_name<T>(self, application_name: T) -> Self where
    T: Into<String>, 

Sets the application name.

pub fn application_uri<T>(self, application_uri: T) -> Self where
    T: Into<String>, 

Sets the application uri

pub fn product_uri<T>(self, product_uri: T) -> Self where
    T: Into<String>, 

Sets the product uri.

pub fn create_sample_keypair(self, create_sample_keypair: bool) -> Self

Sets whether the client should generate its own key pair if there is none found in the pki directory.

pub fn pki_dir<T>(self, pki_dir: T) -> Self where
    T: Into<PathBuf>, 

Sets the pki directory where client's own key pair is stored and where /trusted and /rejected server certificates are stored.

pub fn endpoint<T>(self, endpoint_id: T, endpoint: ServerEndpoint) -> Self where
    T: Into<String>, 

Adds an endpoint to the list of endpoints the client knows of.

pub fn endpoints<T>(self, endpoints: Vec<(T, ServerEndpoint)>) -> Self where
    T: Into<String>, 

Adds multiple endpoints to the list of endpoints the client knows of.

pub fn user_token<T>(
    self,
    user_token_id: T,
    user_token: ServerUserToken
) -> Self where
    T: Into<String>, 

Adds a user token to the server.

pub fn discovery_server_url(self, discovery_server_url: Option<String>) -> Self

Sets the discovery server url that this server shall attempt to register itself with.

pub fn host_and_port<T>(self, host: T, port: u16) -> Self where
    T: Into<String>, 

Sets the hostname and port to listen on

pub fn discovery_urls(self, discovery_urls: Vec<String>) -> Self

Discovery endpoint urls - the urls of this server used by clients to get endpoints. If the url is relative, e.g. "/" then the code will make a url for you using the port/host settings as they are at the time this function is executed.

pub fn max_subscriptions(self, max_subscriptions: u32) -> Self

Set the maximum number of subscriptions in a session

pub fn max_monitored_items_per_sub(
    self,
    max_monitored_items_per_sub: u32
) -> Self

Set the maximum number of monitored items per subscription

pub fn max_array_length(self, max_array_length: u32) -> Self

Set the max array length in elements

pub fn max_string_length(self, max_string_length: u32) -> Self

Set the max string length in characters, i.e. if you set max to 1000 characters, then with UTF-8 encoding potentially that's 4000 bytes.

pub fn max_byte_string_length(self, max_byte_string_length: u32) -> Self

Set the max bytestring length in bytes

pub fn trust_client_certs(self) -> Self

Sets the server to automatically trust client certs. This subverts the authentication during handshake, so only do this if you understand the risks.

pub fn clients_can_modify_address_space(self) -> Self

Set that clients can modify the address space, i.e. they can add or remove nodes through the node management service. By default, they cannot.
