The common wisdom is that Rust libraries should support some old Rust compilers. However, just how old is an open question ! Recently rand bumped MSRV to 1.32.0, which was perceived by some as tad too young for such a widely used crate. I wonder if folks can share their experience with this?
The most interesting for me are external constraints (I can’t use rand 0.7 because my distro only ships Rust 1.28), but something like “I maintain library with declared MSRV 1.28” is interesting as well!
