Lightweight currency conversion library.
This [Rust] crate is a port of the Cashify npm package from the same author. API is not the same.
Simply add the corresponding entry to your Cargo.toml dependency list:
toml
[dependencies]
cashify = "0.1"
The following example uses Serde JSON as strongly typed data structures. Instead of manually specifying rates, you can obtain them from an API, like Exchange Rates API.
```rust use std::collections::HashMap; use serde::{Deserialize, Serialize}; use serde_json::Result; use cashify::{convert};
struct Rates<'a>{ base: &'a str, rates: HashMap<&'a str, f64> }
fn main() -> Result<()> { let data = r#"{ "base": "EUR", "rates": { "GBP": 0.92, "EUR": 1 } }"#;
let r: Rates = serde_json::from_str(data)?;
println!("The result is: {}", convert(10.0, "EUR", "GBP", r.base, r.rates));
Ok(())
} ```
The goal is to try and implement as much features from the original Cashify as possible.
