#![cfg(test)]

//! `@computed(params: <Type>?)` — the parameterized form of `@computed`.
//! Bare `@computed` coverage lives in `tests_computed`/`tests_types`;
//! this file is scoped to the params argument: acceptance, the
//! required-`?` rule, garbage argument forms, and the schema-wide
//! params-type resolution rules in `validate::computed`.
