Crate lua_rs_hlua_shim 

A drop-in subset of the hlua 0.4 embedding API, backed by the pure-Rust lua-rs VM instead of the C library.

The goal is source compatibility: a consumer that does use lua_rs_hlua_shim as hlua; should compile and run against lua-rs without touching its own code. The implemented surface is the part exercised by authoscope — Lua, functionN, AnyLuaValue and friends, LuaFunction, and StringInLua. It is intentionally not the whole hlua API.

Sandboxing note: lua-rs’s runtime opens the full standard library, whereas hlua consumers typically open only string. This is acceptable for a compatibility spike but widens the sandbox; restricting the opened libraries is tracked as future work.

Structs

AnyLuaString

A byte string that may not be valid UTF-8, mirroring hlua::AnyLuaString.

FnHandle

The concrete L we instantiate LuaFunction with: a live borrow of the VM plus the global name to call.

Lua

A Lua state with the standard libraries installed.

LuaError

Error returned by Lua::execute and LuaFunction::call_with_args.

LuaFunction

A handle to a global Lua function, kept by name so it can be re-fetched and called. Mirrors hlua::LuaFunction<L> (single type parameter).

StringInLua

Mirror of hlua::StringInLua<L>: owns the read string and derefs to str.

Enums

AnyHashableLuaValue

The hashable projection used for Lua table keys, mirroring hlua::AnyHashableLuaValue. Numbers narrow to i32 exactly as upstream.

AnyLuaValue

Any Lua value, mirroring hlua::AnyLuaValue field-for-field.

Traits

FromExec

The result type produced by Lua::execute. Only () is supported, which is all authoscope requires.
