Bad message for struct deserialized from array that is too short

[dtolnay]

#[macro_use]
extern crate serde_derive;
extern crate serde_json;

#[derive(Deserialize, Debug)]
struct S {
    a: u8,
}

fn main() {
    println!("{}", serde_json::from_str::<S>("[]").unwrap_err());
}

invalid length 0, expected tuple of 1 elements at line 1 column 2

Something like this might be better:

invalid length 0, expected struct S with 1 element at line 1 column 2
