I have a (large-ish) project of about 20 library crates and 15 binaries. I'm considering moving this into a workspace and have read up on the documentation - but am slightly scared by the seeming lack of using different compiler flags:
In particular I have a few library crates that are very performance sensitivt - they are compiled at high optimization level and using wide avx instructions (sleef primitive math function also used - linking a c++ lib).
However - to save compilation time I do not want to compile all of the other lib crates and binaries using the same compiler settings.
To my question: Is it possible to sett different compiler flags for different crates in a workspace (it specifies that the profile* part is not respected from the sub crates) or do I have to keep using multiple crates outside a workspace to achieve this?
