Compilation error on aarch64

[realaravinth]

I was trying to compile a module on a Raspberry Pi(aarch64) and I encountered the following error:

  --> /srv/mcaptchaguard/.cargo/registry/src/github.com-1ecc6299db9ec823/redis-module-0.21.0/src/context/mod.rs:175:21
    |
175 |                     s.as_ptr() as *const i8,
    |                     ^^^^^^^^^^^^^^^^^^^^^^^ expected `u8`, found `i8`
    |
    = note: expected raw pointer `*const u8`
               found raw pointer `*const i8`

I applied the suggested fix and the compilation succeeded.

Rust doc says std::os::raw::c_char can either be i8 or u8 but I don't understand why i8 would fail to compile.

Here's the module source code

The same module compiles fine on x86_64.

Hi @realaravinth, I have reproduced this now and will look into it.

The fix was simple; you can use the PR branch if you're in a hurry or wait a bit until it's merged.

Alright, thanks for the fix!
