Fields

callstack_id: Option<u64>

self_allocated: Option<u64>

bytes allocated at this callstack.

self_freed: Option<u64>

bytes allocated at this callstack that have been freed.

self_max: Option<u64>

Bytes allocated by this callstack but not freed at the time the malloc heap usage of this process was maximal. This is only set if dump_at_max is true in HeapprofdConfig. In that case, self_allocated, self_freed and self_idle will not be set.

self_max_count: Option<u64>

Number of allocations that were sampled at this callstack but not freed at the time the malloc heap usage of this process was maximal. This is only set if dump_at_max is true in HeapprofdConfig. In that case, self_allocated, self_freed and self_idle will not be set.

timestamp: Option<u64>

timestamp [opt]

alloc_count: Option<u64>

Number of allocations that were sampled at this callstack.

free_count: Option<u64>

Number of allocations that were sampled at this callstack that have been freed.

Implementations

impl HeapSample

pub fn callstack_id(&self) -> u64

Returns the value of callstack_id, or the default value if callstack_id is unset.

pub fn self_allocated(&self) -> u64

Returns the value of self_allocated, or the default value if self_allocated is unset.

pub fn self_freed(&self) -> u64

Returns the value of self_freed, or the default value if self_freed is unset.

pub fn timestamp(&self) -> u64

Returns the value of timestamp, or the default value if timestamp is unset.

pub fn alloc_count(&self) -> u64

Returns the value of alloc_count, or the default value if alloc_count is unset.

pub fn free_count(&self) -> u64

Returns the value of free_count, or the default value if free_count is unset.

pub fn self_max(&self) -> u64

Returns the value of self_max, or the default value if self_max is unset.

pub fn self_max_count(&self) -> u64

Returns the value of self_max_count, or the default value if self_max_count is unset.

Trait Implementations

impl Clone for HeapSample

fn clone(&self) -> HeapSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeapSample

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

Formats the value using the given formatter.

impl Default for HeapSample

fn default() -> HeapSample

Returns the “default value” for a type.

impl Message for HeapSample

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for HeapSample

fn eq(&self, other: &HeapSample) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
