Function nom_tracable::cumulative_histogram

source · 
pub fn cumulative_histogram()
Expand description

Show cumulative histogram of parser call count.

The call count includes the counts of children parsers.

The statistics information to generate histogram is reset at each parser call. Therefore cumulative_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()));
    cumulative_histogram(); // Show cumulative histogram of "1" parsing

    let ret = term(LocatedSpan::new_extra("11", TracableInfo::new()));
    cumulative_histogram(); // Show cumulative histogram of "11" parsing
