Foundation

use-predicate provides tiny helpers for running multiple predicates against a single value: all, any, not, and count.

Example

use use_predicate::{all, any, count, not};

let predicates: [fn(&i32) -> bool; 2] = [|value| *value > 0, |value| *value % 2 == 0];

assert!(all(&4, &predicates));
assert!(any(&3, &predicates));
assert_eq!(count(&4, &predicates), 2);
assert!(not(&3, |value| *value < 0));

When to use directly

Choose use-predicate when predicate composition is the only validation primitive you need.

Scope

• Helpers stay value-first and function-pointer based.
• Rules, constraints, and result types live in adjacent crates.

Status

use-predicate is a pre-1.0 crate with a deliberately small API.
