//! Helper macros for the generated code.
//!
//! The feature-gate helpers are conditionally compiled based on **vld's**
//! features, so when a foreign crate invokes `vld::schema!`, the check uses
//! vld's features instead of the consumer's — eliminating `unexpected_cfgs`
//! warnings.

/// The schema built by `$schema`, cached process-wide on first use
/// (`&'static`). Only for non-generic code.
