Without this line, 49# the proc-macro2 dependency of quote would be the released version of 50# proc-macro2. Quote would implement its traits for types from that proc-macro2, 51# meaning impls would be missing when tested against types from the local 52# proc-macro2. 53# 54# GitHub Actions builds that are in progress at the time that you publish may 55# spuriously fail. This is because they'll be building a local proc-macro2 which 56# carries the second-most-recent version number, pulling in quote which resolves 57# to a dependency on the just-published most recent version number. Thus the 58# patch will fail to apply because the version numbers are different. 59proc-macro2 = { path = "." } 60
