You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: selectable_fields.rs
    path of file: ./repos/prisma-client-rust/crates/generator-shared/src/select_include
    
    the code of the file until where you have to start completion: use prisma_client_rust_sdk::prisma::prisma_models::walkers::FieldWalker;
use proc_macro2::TokenStream;
use quote::*;
u
    
    fn parse(input: ParseStream) -> syn::Result<Self> {
        let contents;
        bracketed!(contents in input);

        Ok(Self(
            Punctuated::<FieldTuple, Token![,]>::parse_terminated(&contents)?
                .into_iter()
                .collect(),
        ))
    }
