Build fails on Mac because .cargo/config.toml has CPU architecture set to haswell

[nastynaz]

Problem: running the examples or otherwise trying to build this repo fails on my machine (Mac M1, Apple Silicon).

The error message is:

'haswell' is not a recognized processor for this target (ignoring processor)

The issue seems to be because of this line:

serenity/.cargo/config.toml

Line 2 in 4e5189c

rustflags = ["-C", "target-cpu=haswell"]

Once I changed it to "target-cpu=native" it worked.

We can remove this file entirely now, as we don't use simd-json anymore.

This is fixed on the next branch, which will be released as serenity 0.13.
