--- + THIS CODE IS NOT STABLE AND WILL CHANGE! + Next todo will be to adjust the parsing and add fuzzer targets
--- + Result type should be used accross the library
--- + Header + various items
--- + 2nd approach to instructions ported from ART
--- + Added new error: OperandAccessError + A,B,C,H and VarArgs can be extracted using vreg module
--- + Instruction iterator and IntoIter support CodeItemAccessor + DexFile now implements methods for describing fields, methods, types and strings
--- + location changed to enum
--- + Changed leb128 parsing to return a Result + Removed unused DexFile field in Method, ClassDataAccessor and Field structs + ClassDataAccessor can be used on all DexFile variants
--- + updated verification flags in DExVerfier
--- + EncodedValue implementation with fuzzing tests + DexFIle is now able to return an UTF8 String without validating the mUTF8
--- + added support to get index from item in dex file
…east for now) --- + string_ids renamed to get_string_ids() + removed unnecessary import in container.rs + mutf8 withstands at least #33554432 fuzzing runs
--- Changes: + decode_leb128p1 will always return i32 from now on + Made file::header::Header cloneable Additions: + Python Extension using pyo3 (feature: "python") + Support is limited to parsing one file and fetching the header for now
--- Changed: + Splitted decode_leb128_off into decode_leb128_adv and decode_leb128_off with slightly different behaviour + DexFile::get<type>_opt applied boundry check using <idx_ty>::MAX instead of u32::MAX + Most structs in dexrs::file::structs are now cloneable + PyDexFileImpl can be created bypassing dex container instances only Additions: + DebugInfo parser (parameter names and positions)
--- + updated initialization of python package to automatically include all types
--- Changes: + Added iterator implementation over parameter names in debug info + Added TypeId interface for Python API
--- Changes: + Added python stubs for each module currently available + Renamed all rust python bindings to begin with py_ Additions: + Added Python API to encode and decode MUTF8 data (currently limited to null-terminated strings)
--- + Removed Field::is_static method from class_accessor + Added DexFile::pretty_type to always return a non-empty string without the need of a result + Instruction::relative_at is now bound to a one-byte extra boundary + ClassAccessor Python API + README updated to reflect API changes
--- + Python API will be generated if cfg(feature = python) + Moved existing Python api into Rust source code base + Python stubs are WIP and don't include constant code flags
--- + vreg module is still missing, but all classes have been added to the Python API + stubs added + Instruction::next now returns an Option<> instead of Result<>
--- + Fixed parsing parameter names in debug info
--- + Fuzzing tests for complex instructions + Two new errors regarding complex instructions + Rename Python API candidate of Instruction to [Py|Rs]DexInstruction + Fix lifetime issue with CodeItemAccessor and Python API + Added Python stubs for vreg sunmodule and added struct definitions
--- + Removed unnecessary import from dex_basic_ops.rs + Added new fuzzing test for code items + Added CatchHandlerData parser to Rust and Python API + New Error to reflect changes in dependencies (+leb128fmt) for signed variable integers + Added leb128 Python API
--- This should finish #4
