-Subject: [PATCH] [bindings] Use v8::Array::Iterate for converting script
- wrappables
-
-This changes CreateIDLSequenceFromV8Array to use the new
-v8::Array::Iterate() operation.
-This speeds up the "execBundles" part of the microbenchmark
-at crbug.com/dawn/1858 by around 3x.
-This depends on crrev.com/c/4846594 landing (and rolling) first.
-
-This is a slight re-work of https://crrev.com/c/4847447/3,
-originally by jkummerow@chromium.org
-
