Implementations

impl PageMetrics

fn new() -> Self

fn with_repetition_level_histogram(self, max_level: i16) -> Self

Initialize the repetition level histogram

fn with_definition_level_histogram(self, max_level: i16) -> Self

Initialize the definition level histogram

fn new_page(&mut self)

Resets the state of this PageMetrics to the initial state. If histograms have been initialized their contents will be reset to zero.
