enum DecodeError

Why bytes could not be decoded into a value ([С §9.4]).

Example:

use std.ser { decode, fromHex }

data Person {
  id: i64
  name: str
}

fn main() io {
  // 0801: only field 1 (id = 1) is present
  let raw = fromHex("0801")!
  match decode<Person>(&raw) {
    Person p => print("{p.name}")
    DecodeError.Missing m => print("missing {m}")
    DecodeError.Invalid _ => print("invalid")
    DecodeError.Malformed _ => print("malformed")
  }
}

`Missing(field: str)`	A required field is absent; `field` is `Type.field`.
`Invalid(msg: str)`	The value violates an invariant or a refined type, or is out of range for its type.
`Malformed(msg: str)`	The input is not a well-formed message of the format.
