Examples

This crate enables choosing a type based on a compile-time constant, just like std::conditional_t in C++.

use condtype::CondType;

let str: CondType<true,  &str, i32> = "hello";
let int: CondType<false, &str, i32> = 42;

// Unsized types are also supported:
let str: &CondType<true, str, [u8]> = "world";

Install

This crate is available on crates.io and can be used by running the following cargo command in your project directory:

or by manually adding the following to your project's Cargo.toml:
