from_as

Rust traits and derive macros for reading and writing files for types that implement serde.

Available on crates.io

toml from_as = "0.2.0"

This crate provides two traits: FromFile and AsFile. FromFile is used for getting types from a file. AsFile is used for writing types to a file.

The traits can be used for writing json, yaml, and toml files.

Example

```rust #[macro_use] extern crate serde;

use std::io::{Read, Write};
use std::convert::TryFrom;
use from_as::*;

#[derive(Debug, Deserialize, Serialize, AsFile, FromFile)]
struct Attribute {
    name: String,
}

fn main() {
    let attr = Attribute { 
        name: "attr_name".into()
    };

    // Write to the example directory.
    attr.as_file("./examples/attr.json").unwrap();

    let attr = Attribute::from_file("./examples/attr.json").unwrap();
    println!("{:#?}", attr);

    // For writing a prettified version.
    attr.as_file_pretty("./examples/attr.json").uwnrap();
}

```
