Function swipc_gen::gen_rust_code::format_ret_ty

fn format_ret_ty(
    ret: &[(Alias, Option<String>)], 
    server: bool
) -> Result<String, Error>

Format the return type of a function.

• If there's 0 return types, then the return type will be ().
• If there's only 1 return type, then that type will be passed directly as the return type.
• If there's 2 or more arguments, then the return type will be a tuple of those types.

IPC Buffers are skipped from the return types, since they are handled by the argument formatter instead. Buffers are passed as mutable reference arguments.

See get_type to find the mapping of a SwIPC type to a Rust type.
