Hi guys  
What difference between creating predicate instances like that

```auto
let predicate = Predicate::new(code) // and which code I should pass here?

```

and that

```auto
let predicate = Predicate::load_from("./out/debug/predicate.bin").unwrap();

```

`::load_from` loads the contents of the given file as the predicate code, while `::new` accepts `Vec<u8>` as the code. The code is the same, the difference is just who does the predicate `.bin` reading – the user or the SDK.

You can find an example using `::load_from` here: [fuels-rs/lib.rs at 358364cefdb02a2d7835be03af1e810f3a6d64f5 · FuelLabs/fuels-rs · GitHub](https://github.com/FuelLabs/fuels-rs/blob/358364cefdb02a2d7835be03af1e810f3a6d64f5/examples/predicates/src/lib.rs#L53)

Here is an example using `::new`:

```rust
 abigen!(Predicate(
      name = "MyPredicate",
      abi = "predicate_basic/out/debug/predicate_basic-abi.json"
  ));

  let path_to_predicate_binary = "predicate_basic/out/debug/predicate_basic.bin";

  let the_predicate_code = std::fs::read(path_to_predicate_binary)?;

  let predicate = MyPredicate::new(the_predicate_code);

```
