1//! This is a place for re-usable Saluki-only defaults.
2//!
3//! Important: this is *not* a place where we should restate Datadog Agent schema-derived defaults.
4//! Defaults that flow from the Datadog schema are defined by codegen in the appropriate crate. We
5//! only want the definitive codegen defaults rather than restating values that can drift (see
6//! #1802).
