Trace is an entry of trace format. https://github.com/catapult-project/catapult/tree/master/tracing

func (TraceEvent) HighAtDimension

func (x TraceEvent) HighAtDimension(d uint64) int64

HighAtDimension returns an integer representing the higher bound at the requested dimension.

func (TraceEvent) ID

func (x TraceEvent) ID() uint64

ID should be a unique ID representing this interval. This is used to identify which interval to delete from the tree if there are duplicates.

func (TraceEvent) LowAtDimension

func (x TraceEvent) LowAtDimension(d uint64) int64

LowAtDimension returns an integer representing the lower bound at the requested dimension.

func (TraceEvent) OverlapsAtDimension

func (mi TraceEvent) OverlapsAtDimension(iv augmentedtree.Interval, dimension uint64) bool

OverlapsAtDimension should return a bool indicating if the provided interval overlaps this interval at the dimension requested.

type TraceEvents

type TraceEvents []TraceEvent

func (TraceEvents) Len

func (t TraceEvents) Len() int

func (TraceEvents) Less

func (t TraceEvents) Less(i, j int) bool

func (TraceEvents) Swap

func (t TraceEvents) Swap(i, j int)
