# `currency-converter`

A command line tool written in Rust to convert between currencies.

## Usage

```
$ currency-converter 1 eur in usd
1 EUR ⟶ 1.17 USD
```

## Configuration

- By default, one API is used to fetch the conversion rate. Additional providers can be enabled by passing their API access keys. The tool averages the results.
- By default, 2 decimal places are printed. By using `--precise`, more decimals might be shown, depending on the conversion rates fetched from the rate providers.
- Stats can be shown with `--stats`.

All configuration options are shown in the `--help` output:
