Crate agent_data_plane_config_system 

The configuration system: translation and subscription of external configuration sources into an ADP-typed model.

This crate turns configuration sources into SalukiConfiguration:

• the typed Datadog source (DatadogConfiguration), whose supported keys the generated drive feeds to DatadogTranslator (a DatadogConfigWitness) one key at a time, and
• the Saluki-schema-only source (SalukiOnly), whose values seed the fields the Datadog schema does not cover.

ConfigurationSystem is the entry point: it translates a raw source map into the initial configuration and, when the map streams updates, keeps that configuration current. This is the only ADP production crate that bridges the source configuration to the model; it constructs no components and does not depend on saluki-components.

Sources are layered as SourceTrees, which keep each value together with the provenance of that value. That is what lets a configuration producer’s own defaults be layered over local configuration without shadowing it, and what lets translation resolve a setting whose meaning depends on whether it was set explicitly.

Structs

ConfigurationSystem

The runtime configuration, translated from the raw sources and kept current.

EnvironmentProvider

LoadedConfiguration

Local configuration prepared before a runtime authority is selected.

Enums

EnvPrecedence

Where environment variables sit relative to the configuration file.

Error

An error building the translated configuration from the raw sources.
