pub const RUNTIME_WARNING_CAP: usize = 64;Expand description
How many RuntimeWarnings one flow accumulates between drains before
it stops recording them.
A cap rather than unbounded growth, per this project’s standing rule
that any accumulating loop needs a limit: an unset temp read inside a
while loop is exactly the shape that would otherwise grow forever.
Dropping the overflow is right for a warning — the first ones already
say everything the author needs.
