Function fixed_width::to_string

pub fn to_string<T: FixedWidth + Serialize>(record: &T) -> Result<String>

Serializes the given type that implements FixedWidth and Serialize to a String.

Example

use serde_derive::Serialize;
use serde;
use fixed_width::{FieldSet, FixedWidth};

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

impl FixedWidth for Record {
    fn fields() -> FieldSet {
        FieldSet::Seq(vec![
            FieldSet::new_field(0..4),
            FieldSet::new_field(4..8),
        ])
    }
}

let record = Record { name: "Carl".to_string(), room: 1234 };
let s = fixed_width::to_string(&record).unwrap();

assert_eq!(s, "Carl1234");
