Trait hyperbole::field::IsoDecode

pub trait IsoDecode {
    type Repr: DeserializeOwned;
    fn from_repr(repr: Self::Repr) -> Self;
}

Types with an alternate representation that is DeserializeOwned.

For hlists, the deserialization format is equivalent to a struct with the same fields:

use hyperbole::{field::IsoDecode, zoom, R};
use serde::Deserialize;

#[derive(Deserialize)]
struct MyRequest {
    a: String,
    b: u32,
    c: f32,
}

let repr = r#"{"a":"hello-worldo","b":32324,"c":345345.34}"#;

let my_req: MyRequest = serde_json::from_str(repr).unwrap();

let my_req_r: R![a: String, b: u32, c: f32] = serde_json::from_str(repr)
    .map(IsoDecode::from_repr)
    .unwrap();

assert_eq!(my_req.a, *zoom![&my_req_r.a]);
assert_eq!(my_req.b, *zoom![&my_req_r.b]);
assert_eq!(my_req.c, *zoom![&my_req_r.c]);
