Trait Implementations

impl Debug for Statistics

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<MutableStatistics> for Statistics

fn from(s: MutableStatistics) -> Statistics

Converts to this type from the input type.

impl PartialEq<Statistics> for Statistics

fn eq(&self, other: &Statistics) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
