Struct ConfigBuilder

pub struct ConfigBuilder { /* private fields */ }

Used to create a Config struct for creating crate::Client instances.

For usage examples see:

• Creating service endpoints
• Configuring a persistent data store
• Configuring the streaming data source
• Configuring events sent to LaunchDarkly

Implementations

impl ConfigBuilder

pub fn new(sdk_key: &str) -> Self

Create a new instance of the ConfigBuilder with the provided sdk_key.

pub fn service_endpoints(self, builder: &ServiceEndpointsBuilder) -> Self

Set the URLs to use for this client. For usage see ServiceEndpointsBuilder

pub fn data_store(self, builder: &dyn DataStoreFactory) -> Self

Set the data store to use for this client.

By default, the SDK uses an in-memory data store. For a persistent store, see PersistentDataStoreBuilder.

pub fn data_source(self, builder: &dyn DataSourceFactory) -> Self

Set the data source to use for this client. For the streaming data source, see StreamingDataSourceBuilder.

If offline mode is enabled, this data source will be ignored.

pub fn event_processor(self, builder: &dyn EventProcessorFactory) -> Self

Set the event processor to use for this client. For usage see EventProcessorBuilder.

If offline mode is enabled, this event processor will be ignored.

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

Whether the client should be initialized in offline mode.

In offline mode, default values are returned for all flags and no remote network requests are made. By default, this is false.

pub fn daemon_mode(self, enable: bool) -> Self

Whether the client should operate in daemon mode.

In daemon mode, the client will not receive updates directly from LaunchDarkly. Instead, the client will rely on the data store to provide the latest feature flag values. By default, this is false.

pub fn application_info(self, application_info: ApplicationInfo) -> Self

Provides configuration of application metadata.

These properties are optional and informational. They may be used in LaunchDarkly analytics or other product features, but they do not affect feature flag evaluations.

pub fn build(self) -> Result<Config, BuildError>

Create a new instance of Config based on the ConfigBuilder configuration.
