@ -77,11 +77,12 @@ There are some caveats to the panic / abort guarantee, however:
memory.
* The internal Lua allocator is set to use `realloc` from `libc`, but it is
wrapped in such a way that OOM errors are guaranteed to *abort*. This is
not currently such a big deal, as this matches the behavior of Rust itself.
This allows the internals of `rlua` to, in certain cases, call 'm' Lua C API
functions with the garbage collector disabled and know that these cannot
error. Eventually, `rlua` will support memory limits on scripts, and those
memory limits will cause regular memory errors rather than OOM aborts.
not currently such a huge deal outside of untrusted scripts, as this matches

Yet another goal of the library is to, in all cases, safely handle panics
generated by Rust callbacks. Panic unwinds in Rust callbacks should currently
