Function fuels_core::code_gen::functions_gen::expand_function

pub fn expand_function(
    function: &ABIFunction,
    types: &HashMap<usize, TypeDeclaration>
) -> Result<TokenStream, Error>

Functions used by the Abigen to expand functions defined in an ABI spec. Transforms a function defined in ABIFunction into a TokenStream that represents that same function signature as a Rust-native function declaration.

The actual logic inside the function is the function method_hash under Contract, which is responsible for encoding the function selector and the function parameters that will be used in the actual contract call.
