Struct StatsSetRef

pub struct StatsSetRef<'a> { /* private fields */ }

Reference to an array’s StatsSet. Can be used to get and mutate the underlying stats.

Constructed by calling ArrayStats::to_ref.

Trait Implementations

impl StatsProvider for StatsSetRef<'_>

fn len(&self) -> usize

Count of stored stats with known values.

fn is_empty(&self) -> bool

Predicate equivalent to a len of zero.
