This patch enhances gccrs’ support for Rust’s Box type by enabling it to handle Dynamically Sized Types (DSTs). It also refines the auto-deref mechanism for Box, ensuring method dispatch, indexing, and tuple field access function correctly. Changes include modifications to how DST guards are handled, fat pointer creation, and expression type checking.
