toRaw

ToRaw is a function in the programming language Lua that is used to convert a userdata value to its raw form. Userdata in Lua is a type that allows the embedding of C data within Lua. When userdata is created, it is often associated with a metatable that defines its behavior. The toRaw function is particularly useful in scenarios where the metatable has overridden the default behavior of userdata, and the raw form of the userdata is needed.

The syntax for using toRaw is straightforward:

```lua

raw = toRaw(userdata)

```

Here, `userdata` is the userdata value you want to convert, and `raw` will be the raw form of that userdata.

The primary use case for toRaw is when you need to perform operations that are not affected by the metatable associated with the userdata. This can be important for tasks such as comparison, equality checking, or other operations where the metatable's behavior might interfere.

It's important to note that toRaw does not modify the original userdata; it simply returns a new value that represents the raw form of the userdata. If the userdata does not have a metatable, calling toRaw on it will return the userdata itself.

ToRaw is part of the LuaJIT library, which is a high-performance Just-In-Time (JIT) compiler for the Lua programming language. It is not a standard function in the base Lua distribution but is available in LuaJIT, making it a valuable tool for developers working with LuaJIT.
