Hello all,

How do we get rust crates checksums?

For example on latest rust update to 1.64.0 several ports were fixed by
updating some problematic crates:

---
(...)
 [[package]]
 name = "socket2"
-version = "0.3.11"
+version = "0.3.19"
 source = "registry+https://github.com/rust-lang/crates.io-index"
-checksum =
"e8b74de517221a2cb01a53349cf54182acdc31a074727d3079068448c0676d85"
+checksum =
"122e570113d28d773067fab24266b66753f6ea915758651696b6e35e49f88d6e"
(...)
---

Thanks,
