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.
