Struct StackStats 

pub struct StackStats {
    pub allocated_bytes: u64,
    pub num_allocations: u64,
    pub freed_bytes: u64,
    pub num_frees: u64,
    /* private fields */
}

Central struct collecting stats about each stack trace

Fields

allocated_bytes: u64

num_allocations: u64

freed_bytes: u64

num_frees: u64

Implementations

impl StackStats

pub fn retained_profiled_bytes(&self) -> u64

The number of “retained” bytes as seen by this stack from sampling

pub fn rich_report( &self, profiler: &YingProfiler, with_filenames: bool, expand_frame: bool, ) -> String

Create a rich multi-line report of this StackStats

• profiler: The &YING_ALLOC or global static defined to enable this profiler
• with_filenames - if True, include source filename in stack trace
• expand_frame - if True, include inlined symbols for each frame in each stack trace

pub fn dtrace_report( &self, profiler: &YingProfiler, measurement: Measurement, ) -> String

Creates a really simple dtrace-compatible multi line string report, with a single measurement at the end. An empty line will be appended at the end. DTrace reports always have inlining > turned off.

• profiler: The &YING_ALLOC or global static defined to enable this profiler
• measurement - enum for what to measure, allocated bytes or retained bytes

Trait Implementations

impl Clone for StackStats

fn clone(&self) -> StackStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StackStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
