Crate bluetape_rs_core 

Core validation, string, and numeric helpers.

Prefer the Rust standard library when it already expresses the operation clearly. This crate is for small repeated backend-service patterns.

use bluetape_rs_core::{require_in_range, require_not_blank};

let name = require_not_blank("name", "bluetape").expect("name");
let port = require_in_range("port", 8080, 1, 65_535).expect("port");

assert_eq!(name, "bluetape");
assert_eq!(port, 8080);
