   = note: the type `milli::documents::Error` does not implement `Borrow`, so calling `borrow` on `&milli::documents::Error` copies the reference, which does not do anything and can be removed
   = note: `-D noop-method-call` implied by `-D warnings`

error: could not compile `meilisearch-types` (lib) due to previous error
warning: build failed, waiting for other jobs to finish...
