Function to_slice 

pub fn to_slice<T>(out: &mut [u8], value: &T) -> Result<usize, Error>
where
    T: ?Sized + Encode<Binary>,

Encode the given value to the given slice using the default Encoding and return the number of bytes encoded.

Examples

use musli::{Decode, Encode};
use musli::packed;

#[derive(Decode, Encode)]
struct Person {
    name: String,
    age: u32,
}

let mut data = Vec::new();
data.resize(128, 0);

let w = packed::to_slice(&mut data[..], &Person {
    name: "Aristotle".to_string(),
    age: 61,
})?;

assert!(w > 0);

let person: Person = packed::from_slice(&data[..w])?;
assert_eq!(person.name, "Aristotle");
assert_eq!(person.age, 61);
