fuels makes use of the ABIEncoder and the ABIDecoder . Token . This is commonly done by implementing the Tokenizable trait. ParamType describing the schema of the type in question. This is commonly done by implementing the Parameterize trait. fuels also contains implementations for: Tokenizable for the fuels-owned types listed here as well as for some foreign types (such as u8, u16, std::vec::Vec<T: Tokenizable>, etc.). Parameterize for the fuels-owned types listed here as well as for some foreign types (such as u8, u16, std::vec::Vec<T: Parameterize>, etc.). Tokenizable and Parameterize can be derived for structs and enums if all inner types implement the derived traits: use fuels::macros::{Parameterize, Tokenizable};
#[derive(Parameterize, Tokenizable)]
struct MyStruct {
field_a: u8,
}
#[derive(Parameterize, Tokenizable)]
enum SomeEnum {
A(MyStruct),
B(Vec<u64>),
}fuels package is accessible through ::fuels. If this is not the case then the derivation macro needs to be given the locations of fuels::types and fuels::core. #[derive(Parameterize, Tokenizable)]
#[FuelsCorePath = "fuels_core_elsewhere"]
#[FuelsTypesPath = "fuels_types_elsewhere"]
