Suggested change

versioning: 'semver',

why? crate datasource is setting crate versioning which is a little different than semver

renovate/lib/modules/datasource/crate/index.ts

Line 52 in 991fdbf

override defaultVersioning = cargoVersioning.id;

[viceice]

does this work on bazel? if yes it should set no version instead of invalid

[viceice]

not clear, is this supported or not
