Function fixed_width::from_bytes

pub fn from_bytes<'de, T>(b: &'de [u8]) -> Result<T, Error> where
    T: FixedWidth + Deserialize<'de>, 

Deserializes a &[u8] into the given type that implements FixedWidth and Deserialize.

Example

#[macro_use]
extern crate serde_derive;
extern crate serde;
extern crate fixed_width;
use fixed_width::{Field, FixedWidth};

#[derive(Deserialize)]
struct Record {
    pub name: String,
    pub room: usize,
}

impl FixedWidth for Record {
    fn fields() -> Vec<Field> {
        vec![
            Field::default().range(0..4),
            Field::default().range(4..8),
        ]
    }
}

fn main() {
    let b = b"Carl1234";
    let record: Record = fixed_width::from_bytes(b).unwrap();

    assert_eq!(record.name, "Carl");
    assert_eq!(record.room, 1234);
}
