utilz

A zero-dependency extension trait crate for Rust. Sick of writing if let Some(x) all the time? Want .tap(), .toggle(), or .if_ok()? This crate gives you clean, readable, expressive utility extensions without the bloat.

Features

Lightweight extensions for common types like Option, Result, Vec, bool, str, HashMap, and more!

Installation

# Cargo.toml
[dependencies]
utilz-rs = "0.1"

No dependencies. No macros. Just clean, simple, useful sugar.

Usage Examples

OptionUtils

use rust_utils_plus::OptionUtils;

let val = Some("hello");
val.if_some(|s| println!("Got {}", s));

let fallback = val.or_default_with("default");

ResultUtils

use rust_utils_plus::ResultUtils;

let res: Result<i32, &str> = Ok(42);
res.if_ok(|v| println!("Success: {v}"));
res.if_err(|e| println!("Error: {e}"));

BoolUtils

use rust_utils_plus::BoolUtils;

let mut flag = true;
flag.toggle(); // becomes false

let val = flag.then_val("Yes"); // None

VecUtils

use rust_utils_plus::VecUtils;

let mut list = vec![];
list.push_if(10, true);
list.push_if_with(false, || expensive_computation());

StrUtils

use rust_utils_plus::StrUtils;

let s = "hello world";
assert!(s.contains_all(["hello", "world"]));
println!("{}", s.to_title_case()); // "Hello world"

DurationUtils

use rust_utils_plus::DurationUtils;

let d = Duration::from_secs(3661);
println!("{}", d.pretty()); // "1h 1m 1s"
