v0.10.0

What's Changed

For full changelog see changes in v0.10.0-beta.1, v0.10.0-beta.2 and v0.10.0-rc.1 versions.

Most notable changes since v0.9:

• No more 'lua lifetime
• Send + Sync with send feature flag
• Lua::exec_raw helper to execute low-level Lua C API code
• LuaNativeFn/LuaNativeFnMut/LuaNativeAsyncFn traits for using in Function::wrap
• Setting metatable for Lua builtin types (number/string/function/etc)

v0.10.0-rc.1

What's Changed

• Lua::scope is back
• Support yielding from hooks for Lua 5.3+
• Support setting metatable for Lua builtin types (number/string/function/etc)
• Added LuaNativeFn/LuaNativeFnMut/LuaNativeAsyncFn traits for using in Function::wrap
• Added Error::chain method to return iterator over nested errors
• Added Lua::exec_raw helper to execute low-level Lua C API code
• Added Either<L, R> enum to combine two types into a single one
• Added a new Buffer type for Luau
• Added Value::is_error and Value::as_error helpers
• Added Value::Other variant to represent unknown Lua types (eg LuaJIT CDATA)
• Added (optional) anyhow feature to implement IntoLua for anyhow::Error
• Added IntoLua/FromLua for OsString/OsStr and PathBuf/Path by @psentee in #459

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.

• Lua::replace_registry_value takes &mut RegistryKey
