Function make_trait_impl

pub comptime fn make_trait_impl<Env1, Env2>(
    s: TypeDefinition,
    trait_name: Quoted,
    function_signature: Quoted,
    for_each_field: fn[Env1](Quoted) -> Quoted,
    join_fields_with: Quoted,
    body: fn[Env2](Quoted) -> Quoted,
) -> Quoted

make_impl is a helper function to make a simple impl, usually while deriving a trait. This impl has a couple assumptions:

  1. The impl only has one function, with the signature function_signature
  2. The trait itself does not have any generics.

While these assumptions are met, make_impl will create an impl from a TypeDefinition, automatically filling in the required generics from the type, along with the where clause. The function body is created by mapping each field with for_each_field and joining the results with join_fields_with. The result of this is passed to the body function for any final processing - e.g. wrapping each field in a StructConstructor { .. } expression.

See derive_eq and derive_default for example usage.
