pub fn histogram()
Expand description
Show histogram of parser call count.
The statistics information to generate histogram is reset at each parser call.
Therefore histogram
should be called before next parser call.
The information is thread independent because it is stored at thread local storage.
let ret = term(LocatedSpan::new_extra("1", TracableInfo::new()));
histogram(); // Show histogram of "1" parsing
let ret = term(LocatedSpan::new_extra("11", TracableInfo::new()));
histogram(); // Show histogram of "11" parsing
