Crate utilz_rs

Utilz

Ergonomic, zero-dependency utility traits for Rust.

This crate provides a collection of extension traits for common Rust types like Option, Result, Vec, bool, &str, HashMap, and more — to make your code cleaner, shorter, and more expressive without relying on macros or external dependencies.

Highlights

• Log – In-memory logger with filtering support

  • .log_info(), .log_warn(), .print_logs(), .set_up_logger(), .clear()…

• OptionUtils – Convenient extensions for Option<T>

  • .if_some(), .or_default_with()

• ResultUtils – Cleaner result handling

  • .if_ok(), .if_err(), .unwrap_or_exit()

• BoolUtils – Fancy conditionals for bool

  • .toggle(), .not(), .then_val(), .if_true(), .if_false()

• VecUtils – Push conditionally into vectors

  • .push_if(), .push_if_with()

• StrUtils – String slice helpers

  • .contains_all(), .contains_any(), .to_title_case()

• MapUtils – Extensions for HashMap

  • .insert_if(), .get_or()

• MemUtils – Reflection-like helpers

  • .type_name(), .mem_size(), .view()

• IdentityUtils – Chainable tap() for debug or logging

• PanicUtils – Exit on None or Err with a message

  • .unwrap_or_exit()

• DurationUtils – Time formatting helpers

  • .pretty() → "1h 2m 3s"

• ConvertUtils – Ergonomic TryFrom helpers

  • .to(), .to_or(), .to_result()

• ClampUtils – Limit a number to a range

  • .clamp_to(min, max)

• NumberUtils – Integer property checks

  • .is_even(), .is_odd()

• IteratorUtils – Iterator fallback logic

  • .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"
