pub fn discard_external_properties()Expand description
Empties the cross-thread typed-property channel, throwing away whatever it holds.
The bus is one channel per process, so a second app built in the same
process inherits every write the first one left queued. A caller that runs
several apps in sequence (a build rendering one page after another, a
server rendering one request after another) calls this between them so each
app starts from its own state. Pair it with
crate::signals::discard_external_signals, which empties the array half.
