I am trying to setup an enum struct to contain cvar handles, variables, and function callbacks for when they are changed, but the compiler is telling me there is a prototype mismatch. I imagine this is similar to the limitations with array members being unable to pass their sizes, so I suppose I shouldn't have expected this work in the first place...

PHP Code:

enum struct PluginData
{
    Handle c_enable;
    int enable;
    
    void EnableChange(Handle convar, const char[] oldValue, const char[] newValue)
    {
        this.enable = StringToInt(newValue);
    }
};
PluginData cVars;
public void OnPluginStart()
{
    cVars.c_enable = CreateConVar("sm_enable", "1.0", "Enable plugin", 0, true, 0.0, true, 1.0);
    HookConVarChange(cVars.c_enable,cVars.EnableChange); //line 22
} 


test.sp(22) : error 100: function prototypes do not match

It's because methods on methodmaps and enum structs have a hidden fourth argument representing the methodmap/struct itself.

So, your EnableChange method's signature is actually this:

void EnableChange(PluginData this, Handle convar, const char[] oldValue, const char[] newValue)

Ah, that makes sense, I should have thought about that.. Thanks
