Struct TraceHandler 

pub struct TraceHandler { /* private fields */ }

Trace Handler convert address into proper stacktraces, apply necessary caching

Main entry point for the trace handler that manages symbol resolution and caching for efficient stack trace processing and visualization.

Implementations

impl TraceHandler

pub fn new() -> Self

pub fn print_stats(&self)

pub fn get_exp_stacked_frames( &mut self, stack_info: &StackInfo, stack_traces: &StackTraceMap<MapData>, group_by_cpu: bool, stacked_pointers: &HashMap<MapData, StackInfoPod, FramePointersPod>, ) -> Vec<StackFrameInfo>

Converts stacks traces into StackFrameInfo structs Uses DWARF-unwound frame pointers from eBPF when available

pub fn get_stacked_frames( &mut self, stack_info: &StackInfo, stack_traces: &StackTraceMap<MapData>, group_by_cpu: bool, ) -> Vec<StackFrameInfo>

Converts stacks traces into StackFrameInfo structs

pub fn get_instruction_pointers( &mut self, stack_info: &StackInfo, stack_traces: &StackTraceMap<MapData>, ) -> (Option<Vec<u64>>, Option<Vec<u64>>)

Extract stacks from StackTraceMaps (kernel’s implementation only support FP unwinding)
