  "message": "borrowck: Introduce BlameConstraint::to_obligation_cause_from_path()\n\nBefore this commit, `BlameConstraint` is a bit hard to understand at\nfirst, because of its `ObligationCause` field. In practice,\n`BlameConstraint` is just a slimmed down version of an\n`OutlivesConstraint` from `Vec\u003cOutlivesConstraint\u003e`.\n\nThe artificial `ObligationCause` is only needed in one place. Rather\nthan having that exception polute the lower level analysis, bubble it up\nas much as we can. That way, it becomes clearer what `BlameConstraint`\nactually is.\n\nFor reference, `ObligationCause` was introdued by 93ab12eeaba2c, but the\ncodebase looked quite different back then.\n",
