Without this line, 47# the proc-macro2 dependency of quote would be the released version of 48# proc-macro2. Quote would implement its traits for types from that proc-macro2, 49# meaning impls would be missing when tested against types from the local 50# proc-macro2. 51# 52# GitHub Actions builds that are in progress at the time that you publish may 53# spuriously fail. This is because they'll be building a local proc-macro2 which 54# carries the second-most-recent version number, pulling in quote which resolves 55# to a dependency on the just-published most recent version number. Thus the 56# patch will fail to apply because the version numbers are different. 57proc-macro2 = { path = "." } 58
