  "message": "Add helper functions to iterate over ChainedStructs\n\nThis CL adds two helpers for more ergonomic processing of\nChainedStructs.\n\n1. FindInChain(): Iterates through the chain and automatically\n   casts the ChainedStruct into the appropriate child type before\n   returning.\n2. ValidateSTypes(): Verifies that the chain only contains structs\n   with sTypes from a pre-defined set. This also allows the caller\n   to specify one-of constraints.\n3. ValidateSingleSType(): Verifies that the chain contains a\n   single struct with a specific sType or is an empty chain. This\n   is a common case of |ValidateSTypes()| and is separated out as\n   a fast-path.\n\nChange-Id: I938df0bf2a9b1800b1105fb7f80fbde20bef8ec8\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/47680\nCommit-Queue: Brian Ho \u003chob@chromium.org\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\n",
