Is clippy's msrv option useful to librsvg?
Clippy's README notes that one can create a clippy.toml
file with a key like msrv = "1.48.0"
to indicate the minimum supported Rust version.
I'm not sure if that only omits suggestions that would only be implementable with newer Rusts, or if it also warns about constructs that would not work on old compilers.
Either way, is this useful to have in the CI?
