Function fixed_width::from_str_with_fields

pub fn from_str_with_fields<'de, T>(
    s: &'de str, 
    fields: Vec<Field>
) -> Result<T, Error> where
    T: Deserialize<'de>, 

Deserializes &str data to the given writer using the provided Fields.

Example

use std::collections::HashMap;
use fixed_width::{Field, from_str_with_fields};

let fields = vec![
    Field::default().range(0..4).name(Some("numbers")),
    Field::default().range(4..8).name(Some("letters")),
];
let mut s = "1234abcd";

let h: HashMap<String, String> = from_str_with_fields(s, fields).unwrap();
assert_eq!(h.get("numbers").unwrap(), "1234");
assert_eq!(h.get("letters").unwrap(), "abcd");
