error[E0635]: unknown feature `proc_macro_span_shrink`

[CMIW]

When trying to compile for rustc 1.70.0 it outputs the following error :

error[E0635]: unknown feature proc_macro_span_shrink
--> ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/proc-macro2-1.0.47/src/lib.rs:92:30
|
92 | feature(proc_macro_span, proc_macro_span_shrink)
| ^^^^^^^^^^^^^^^^^^^^^^

It's solved by running cargo update -p proc-macro2 on CaptureSight/libs/csight-core
