Struct StackSampleDefaults 

pub struct StackSampleDefaults {
    pub source: Option<String>,
    pub primary_descriptor: Option<CounterDescriptor>,
    pub follower_descriptors: Vec<CounterDescriptor>,
}

Per-sequence defaults for StackSample. Lets a producer declare the source and the common timebase / followers once instead of on every sample.

Fields

source: Option<String>

Identifies the profiler that produced these samples, e.g. “linux.perf”, “python.wall”. Recorded once per sampling stream.

primary_descriptor: Option<CounterDescriptor>

Default primary timebase for samples that omit their own.

follower_descriptors: Vec<CounterDescriptor>

Default follower counters, positional with StackSample.follower_weights.

Implementations

impl StackSampleDefaults

pub fn source(&self) -> &str

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

Trait Implementations

impl Clone for StackSampleDefaults

fn clone(&self) -> StackSampleDefaults

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StackSampleDefaults

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

Formats the value using the given formatter.

impl Default for StackSampleDefaults

fn default() -> Self

Returns the “default value” for a type.

impl Message for StackSampleDefaults

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 StackSampleDefaults

fn eq(&self, other: &StackSampleDefaults) -> 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.
