Struct Checked

pub struct Checked<Tx: IntoChecked> { /* private fields */ }

The type describes that the inner transaction was already checked.

All fields are private, and there is no constructor, so it is impossible to create the instance of Checked outside the fuel-tx crate.

The inner data is immutable to prevent modification to invalidate the checking.

If you need to modify an inner state, you need to get inner values (via the Into<(Tx, Tx ::Metadata)> trait), modify them and check again.

Dev note: Avoid serde serialization of this type.

Since checked tx would need to be re-validated on deserialization anyways, it’s cleaner to redo the tx check.
