A trait indicating that this statistic can be used to trigger a statistics change.

Required Methods

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

fn stat_list(&self) -> &'static [&'static (StatDefinition + Sync)]

The list of stats that this trigger applies to.

fn tag_value(&self, stat_id: &StatDefinition, _tag_name: &'static str) -> String

Get the associated tag value for this log. The value must be convertable to a string so it can be stored internally.

Provided Methods

fn condition(&self, _stat_id: &StatDefinition) -> bool

The condition that must be satisfied for this stat to change

fn change(&self, _stat_id: &StatDefinition) -> Option<ChangeType>

The details of the change to make for this stat, if condition returned true.

fn bucket_value(&self, _stat_id: &StatDefinition) -> Option<f64>

The value to be used to sort the statistic into the correct bucket(s).
