# tor-units

Safe wrappers for primitive numeric types.

## Overview

This crate is part of
[Arti](https://gitlab.torproject.org/tpo/core/arti/), a project to
implement [Tor](https://www.torproject.org/) in Rust.
It provides safe wrappers for primitive numeric wrappers used in
other parts of Arti.
In particular, it provides:
  * a bounded i32 with both checked and clamping constructors,
  * an integer milliseconds wrapper with conversion to [`Duration`]
  * an integer seconds wrapper with conversion to [`Duration`]
  * a percentage wrapper, to prevent accidental failure
    to divide by 100.
  * a SendMeVersion which can be compared only.

## Compile-time features

 * `memquota-memcost` -- implement `tor_memquota::HasMemoryCost` for many types.
   (Does not actually force compiling in memory quota tracking;
   that's `memquota` in `tor-memquota` and higher-level crates.)

 * `full` -- Enable all features above.
