Struct AppBootstrapper 

pub struct AppBootstrapper { /* private fields */ }

Early application initialization.

This helper type is used to configure the various low-level shared resources required by the application, such as the logging and metrics subsystems.

Implementations

impl AppBootstrapper

pub fn new() -> Self

Creates a new AppBootstrapper.

The bootstrapper is initialized with a simple logging configuration. Callers that have application-specific logging requirements should follow up with with_logging_configuration to override this default.

pub fn with_metrics_prefix<S: Into<String>>(self, prefix: S) -> Self

Sets the prefix to use for internal metrics.

Defaults to saluki.

pub fn with_metrics_default_level(self, level: Level) -> Self

Sets the default filter level for internal metrics.

Metrics whose level is more verbose than this default are filtered out at flush time. The default also drives the level that the filter is restored to whenever a runtime override is reset.

Defaults to Level::INFO.

pub fn with_logging_configuration( self, logging_config: LoggingConfiguration, ) -> Self

Sets the logging configuration to use during bootstrap.

Replaces the simple default that new installs.

pub async fn bootstrap(self) -> Result<Bootstrap, GenericError>

Executes the bootstrap operation, initializing all configured subsystems.

Returns a Bootstrap containing both a BootstrapGuard (which must be held until the application is ready to shut down) and a Supervisor populated with workers for all background async tasks created during bootstrap. Callers must arrange for the supervisor to run (typically by adding it to a parent supervisor or calling Supervisor::run_with_shutdown) for those workers to make progress.

Errors

If any of the bootstrap steps fail, an error will be returned.
