Number

Create a number schema with number().

use zod_rs::prelude::*;
use serde_json::json;

let schema = number();
assert!(schema.safe_parse(&json!(42.5)).is_ok());
assert!(schema.safe_parse(&json!("42")).is_err());

Validations

min(n) / max(n) — range constraints

let schema = number().min(0.0).max(100.0);
assert!(schema.safe_parse(&json!(50)).is_ok());
assert!(schema.safe_parse(&json!(-1)).is_err());

int() — integer only

let schema = number().int();
assert!(schema.safe_parse(&json!(42)).is_ok());
assert!(schema.safe_parse(&json!(42.5)).is_err());

positive() — must be > 0

let schema = number().positive();
assert!(schema.safe_parse(&json!(1)).is_ok());
assert!(schema.safe_parse(&json!(0)).is_err());

nonnegative() — must be >= 0

let schema = number().nonnegative();
assert!(schema.safe_parse(&json!(0)).is_ok());
assert!(schema.safe_parse(&json!(-1)).is_err());

negative() — must be < 0

let schema = number().negative();
assert!(schema.safe_parse(&json!(-1)).is_ok());

nonpositive() — must be <= 0

let schema = number().nonpositive();
assert!(schema.safe_parse(&json!(0)).is_ok());

finite() — excludes NaN and Infinity

let schema = number().finite();
assert!(schema.safe_parse(&json!(42.0)).is_ok());
