Trait hdrhistogram::iterators::PickyIterator [−][src]
pub trait PickyIterator<T: Counter> { fn pick(
&mut self,
index: usize,
total_count_to_index: u64,
count_at_index: T
) -> Option<PickMetadata>; fn more(&mut self, index_to_pick: usize) -> bool; }
A trait for designing an subset iterator over values in a Histogram
.
Required methods
fn pick(
&mut self,
index: usize,
total_count_to_index: u64,
count_at_index: T
) -> Option<PickMetadata>
[src]
&mut self,
index: usize,
total_count_to_index: u64,
count_at_index: T
) -> Option<PickMetadata>
Return Some
if an IterationValue
should be emitted at this point.
index
is a valid index in the relevant histogram.
This will be called with the same index until it returns None
. This enables modes of
iteration that pick different values represented by the same bucket, for instance.
fn more(&mut self, index_to_pick: usize) -> bool
[src]
Should we keep iterating even though the last index with non-zero count has already been picked at least once?
This will be called on every iteration once the last index with non-zero count has been
picked, even if the index was not advanced in the last iteration (because pick()
returned
Some
).
