pub fn parse_chrome_version(ua: &str) -> Option<Vec<u16>>Expand description
Extract the Chromium version parts from a UA string (... Chrome/146.0.7444.60 ...).
Used to pin a persona to the binary that is actually running. The UA is the only
part of a version claim we control: detectors feature-detect the build — which CSS
properties parse, which window members exist, which JS builtins are present — and
each maps to a release range no UA rewrite can move. Measured against browserscan,
a persona claiming 124 on a 146 binary came back liedCSS/liedJS/liedWindow
with an exact distance of 22.
