Struct pprof::protos::Sample

pub struct Sample {
    pub location_id: Vec<u64>,
    pub value: Vec<i64>,
    pub label: Vec<Label>,
}

Each Sample records values encountered in some program context. The program context is typically a stack trace, perhaps augmented with auxiliary information like the thread-id, some indicator of a higher level request being handled etc.

Fields

location_id: Vec<u64>

The ids recorded here correspond to a Profile.location.id. The leaf is at location_id[0].

value: Vec<i64>

The type and unit of each value is defined by the corresponding entry in Profile.sample_type. All samples must have the same number of values, the same as the length of Profile.sample_type. When aggregating multiple samples into a single sample, the result has a list of values that is the elemntwise sum of the lists of the originals.

label: Vec<Label>

label includes additional context for this sample. It can include things like a thread id, allocation size, etc

Trait Implementations

impl Clone for Sample

fn clone(&self) -> Sample

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sample

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

Formats the value using the given formatter.

impl Default for Sample

fn default() -> Self

Returns the “default value” for a type.

impl Message for Sample

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

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<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

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

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

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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

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

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

impl PartialEq<Sample> for Sample

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
