fn decodeLike

Decodes b as the result type of like (used to decode the value of a durable step when a pipeline resumes on another node). Panics when the bytes do not decode.

Example:

use std.saga
use std.ser { encode }

fn zero() -> i64 => 0

fn main() io {
  let b = encode(&(41 as i64))!
  print("{saga.decodeLike(&b, zero) + 1}")
}
