Trait slog_extlog::stats::StatTrigger

pub trait StatTrigger {
    fn stat_list(&self) -> &[StatDefinitionTagged];
    fn tag_value(
        &self, 
        stat_id: &StatDefinitionTagged, 
        _tag_name: &'static str
    ) -> String;

    fn condition(&self, _stat_id: &StatDefinitionTagged) -> bool { ... }
    fn change(&self, _stat_id: &StatDefinitionTagged) -> Option<ChangeType> { ... }
    fn bucket_value(&self, _stat_id: &StatDefinitionTagged) -> Option<f64> { ... }
}

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

Required methods

fn stat_list(&self) -> &[StatDefinitionTagged]

The list of stats that this trigger applies to.

fn tag_value(
    &self,
    stat_id: &StatDefinitionTagged,
    _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.
