currencyapi_parse

A library to parse currencyapi latest response.

This library doesn't parse the response JSON, it just takes advantage of the regularity in the API. It has some sanity-checks for the regularity so it should be fine at least for casual use.

Usage

Use the [Scanner] to iterate over currency [Entry]s.

Example

```rust

fn main() -> Result<(), Box> {

// sample response from /latest USD & EUR: https://api.currencyapi.com/v3/latest?apikey=&currencies=USD%2CEUR let response = r#"{"meta":{"lastupdatedat":"2022-08-23T23:59:59Z"},"data":{"EUR":{"code":"EUR","value":1.003367},"USD":{"code":"USD","value":1}}}"#;

let currencies = currencyapiparse::Scanner::tryfrom(response)?; for entry in currencies { println!("{} = {:.2}", std::str::from_utf8(&entry.currency)?, response[entry].parse::()? // Entrys can conveniently index the response they come from. ); }

Ok(()) }

```
