conditional-assignment

GitHub Workflow Status (with branch) Crates.io Crates.io (latest)

This is a very simple, small crate to help make conditional assignments more ergonomic.

Intent

The goal is to make the below look a little better.

let condition = 0 < 1;
let outcome = if condition {
    "true"
} else {
    "false"
};

Examples

Basic

Eager

use conditional_assignment::Pick;

let condition = 0 < 1;
let outcome = condition.pick("true", "false");

Lazy

use conditional_assignment::Pick;

let condition = 0 < 1;
let outcome = condition.pick_lazy(
    || {
        // This won't be evaluated and
        // panic when condition is false.
        assert!(condition);
        "true"
    },
    || {
        // This won't be evaluated and
        // panic when condition is true.
        assert!(!condition);
        "false"
    },
);

Minimum Supported Rust Version (MSRV)

According to cargo-msrv, the MSRV is 1.56.1. Given how simple this crate is, I wouldn't be surprised if the MSRV is lower, but I didn't check. Try it!
