Utilz

Ergonomic utility traits for Rust with zero dependencies by default.

utilz provides a curated set of extension traits for common Rust types like Option, Result, Vec, bool, &str, HashMap, and more — to help you write cleaner, shorter, and more expressive code.

---

Highlights

• Log – Simple in-memory logger with optional async support – .log_info(), .log_warn(), .print_logs(), .set_up_logger(), .clear()

• OptionUtils – More ergonomic handling of Option<T> – .if_some(), .or_default_with()

• ResultUtils – Sugar methods for Result<T, E> – .if_ok(), .if_err(), .unwrap_or_exit()

• BoolUtils – Conditionals made fancy – .toggle(), .not(), .then_val(), .if_true(), .if_false()

• VecUtils – Push conditionally into vectors – .push_if(), .push_if_with()

• StrUtils – Extensions for &str – .contains_all(), .contains_any(), .to_title_case()

• MapUtils – HashMap helpers – .insert_if(), .get_or()

• MemUtils – Reflection-like methods – .type_name(), .mem_size(), .view()

• IdentityUtils – Tap-style chaining – .tap()

• PanicUtils – Fatal exit helpers – .unwrap_or_exit()

• DurationUtils – Duration formatting – .pretty() → "1h 2m 3s"

• ConvertUtils – Easy type conversions with TryFrom – .to(), .to_or(), .to_result()

• ClampUtils – Range limiting for numbers – .clamp_to(min, max)

• NumberUtils – Integer extensions – .is_even(), .is_odd()

• IteratorUtils – Fallback logic for iterators – .find_map_or(f, fallback)

✨ Quick Example

use utilz_rs::*;

let value = Some("hi");
value.if_some(|v| println!("Got: {v}"));

let mut enabled = true;
enabled.toggle();

let name = "hello world";
assert!(name.contains_all(["hello", "world"]));

let duration = std::time::Duration::from_secs(3666);
println!("{}", duration.pretty()); // → "1h 1m 6s"

Philosophy

• ✅ 100% Rust standard library
• 🔧 Zero dependencies by default
• 🔌 Async logging via optional feature flag
• 🙌 Opt-in trait imports: use only what you need

Use what you want, ignore the rest. No macros. No surprises.
