v0.10.0-beta.2

Notes

mlua is getting close to v0.10 stable release. Send+Sync works well and hopefully all unsoundness are fixed.

Few (planned) features left:

• Scope support
• Getting/setting metatable for primitives
• Support yielding in hooks for Lua 5.3+ (similar to yielding in Luau interrupt callback)
• Access to raw Lua state (lock protected but unsafe)
• Either<A, B> enum that implements FromLua
• LuaNativeFn trait to wrap Rust functions with non-tuple args (will be used in Function::wrap*)
• More code coverage
• (possibly) IntoLua derive macro

What's Changed

• Updated ThreadStatus enum to include Running and Finished variants.
• Error::CoroutineInactive renamed to Error::CoroutineUnresumable.
• IntoLua/IntoLuaMulti now uses impl trait syntax for args (shorten from a.get::<_, T> to a.get::<T>).
• Removed undocumented Lua::into_static/from_static methods.
• Futures now require Send bound if send feature is enabled.
• Dropped lifetime from UserDataMethods and UserDataFields traits.
• Compiler::compile() now returns Result (Luau).
• Removed Clone requirement from UserDataFields::add_field().
• TableExt and AnyUserDataExt traits were combined into ObjectLike trait.
• Disabled send feature in module mode (since we don't have exclusive access to Lua).
• Chunk::set_environment() takes Table instead of IntoLua type.
• Reduced the compile time contribution of next_key_seed and next_value_seed.
• Reduced the compile time contribution of serde_userdata.
• Performance improvements.

v0.10.0-beta.1

What's Changed

• Dropped 'lua lifetime (subtypes now store a weak reference to Lua)
• Removed (experimental) owned types
• Make Lua types truly Send and Sync (when enabling send feature flag)
• Removed UserData impl for Rc/Arc types ("any" userdata functions can be used instead)
• Lua::replace_registry_value takes &mut RegistryKey
• Lua::scope temporary disabled (will be re-added in the next release)

v0.9.7

What's Changed

• Implemented IntoLua for RegistryKey
• Mark __idiv metamethod as available for Luau
• Added Function::deep_clone() method (Luau)
• Added SerializeOptions::detect_serde_json_arbitrary_precision option
• Added Lua::create_buffer() method (Luau)
• Support serializing buffer type as a byte slice (Luau)
