Can't be used on ARM platform because of error 'is_x86_feature_detected can only be used on x86 and x86_64 targets'

[iav]

Trying to build project for ARM (both aarch64and armv7hf) platforms got an error. It seems there proposedaway to fix:

Compiling v_escape v0.12.0

error:
        is_x86_feature_detected can only be used on x86 and x86_64 targets.
        You can prevent it from being used in other architectures by
        guarding it behind a cfg(target_arch) as follows:

            #[cfg(any(target_arch = "x86", target_arch = "x86_64"))] {
                if is_x86_feature_detected(...) { ... }

It's true. I had not tried it, I thought the macros was defined in other targets. It's just a #[cfg ()] attributte in v_escape/build.rs. Can you do the PR?

[iav]

Sad I am not a programmer at all.
I can run cargo build on ARM platform if somebody else does changes and project to test it.

[zzau13]

b0f839c should fix this issue. Can you confirm it?

[iav]

How can I test it?
Currently I just build another project with dependency v_escape.
How can I tell this project to use this fixed version?

[zzau13]

Use git version

v_htmlescape = { git = "https://github.com/botika/v_escape" }

Thank you!
Seems it work.

Sorry for delay.
