ARM64 Compatibility Issue on macOS (M2 Chip): b64encode Undefined

[0xqbyte]

Description

I encountered a build error while using the github.com/cloudwego/base64x library on my macOS device with an M2 chip. The error indicates that b64encode is undefined in the base64x.go file.

Error Details

../../../../../pkg/mod/github.com/cloudwego/base64x@v0.1.4/base64x.go:90:5: undefined: b64encode

Environment

• OS: macOS Ventura (M2 Chip)
• Go Version: go version go1.x.x darwin/arm64
• Library Version: v0.1.4

Steps to Reproduce

1. Create a simple Go project that uses the github.com/cloudwego/base64x package.
2. Build or run the project on a Mac with an M2 chip (ARM64 architecture).
3. Observe the error.

Expected Behavior

The library should support ARM64 architecture or provide a fallback mechanism.

Actual Behavior

The b64encode function is undefined, which suggests the library might not support ARM64 architecture.

Request

Could you confirm if ARM64 architecture is supported by this library? If not, is there a workaround or planned support for ARM64 devices like M1/M2 chips?

No, not support at present
