use-rule

Named reusable rule primitives for RustUse.

Install

[dependencies]
use-rule = "0.0.1"

Foundation

use-rule provides a Rule<T, F> type for reusable named checks plus a lightweight RuleEvaluation result.

Example

use use_rule::Rule;

let rule = Rule::<i32, _>::new("positive", |value| *value > 0);
let evaluation = rule.evaluate(&42);

assert_eq!(evaluation.name(), "positive");
assert!(evaluation.passed());

When to use directly

Choose use-rule when you want a named reusable check without a broader framework.

Scope

• Rules stay generic over a single input value.
• Evaluation results stay small and explicit.
• Error aggregation and reporting layers are out of scope.

Status

use-rule is a pre-1.0 crate with a deliberately narrow API.
