Overview ¶
Package flamegraph provides a backward-compatible wrapper for perflib/flamegraph. The generator.go file is intentionally left empty because all types and functions are now defined via type aliases in model.go, delegating to perflib/flamegraph.
Package flamegraph provides unified flame graph data structures and utilities. This package delegates to perflib/flamegraph and provides type aliases for backward compatibility.

Functions ¶
func ExtractThreadGroup ¶
ExtractThreadGroup extracts the thread group name by removing trailing numbers and separators.
func IsSwapperThread ¶
IsSwapperThread checks if the thread name indicates a swapper (idle) thread.
func StackToString ¶
StackToString converts a call stack to a semicolon-separated string.
func StringToStack ¶
StringToStack converts a semicolon-separated string back to a call stack.
Types ¶
type CPUAnalysisResult ¶
type CPUAnalysisResult = libfg.CPUAnalysisResult
CPUAnalysisResult holds the complete CPU profiling analysis result.
func NewCPUAnalysisResult ¶
func NewCPUAnalysisResult() *CPUAnalysisResult
NewCPUAnalysisResult creates a new CPUAnalysisResult with initialized maps.
type CallStackEntry ¶
type CallStackEntry = libfg.CallStackEntry
CallStackEntry represents a unique call stack.
func BuildThreadCallStacks ¶
func BuildThreadCallStacks(callStacks map[string]int64, totalSamples int64, maxStacks int) []*CallStackEntry
