Enum Chunk 

pub enum Chunk {
    XOR(XORChunk),
    Histogram(HistogramChunk),
    FloatHistogram(FloatHistogramChunk),
}

A Prometheus chunk.

It can be a XOR chunk, a histogram chunk, or a float histogram chunk.

For now, only the XOR chunk type is fully implemented.

Variants

XOR(XORChunk)

Histogram(HistogramChunk)

FloatHistogram(FloatHistogramChunk)

Implementations

impl Chunk

pub fn new_xor(samples: Vec<XORSample>) -> Self

Creates a Chunk of type XOR.

pub fn as_xor(self) -> Option<XORChunk>

Returns the XOR chunk if it’s a XOR chunk.

pub fn block_chunk_ref(&self) -> Option<u64>

Retuns the block chunk reference.

impl Chunk

pub fn write<W: Write>(&self, writer: &mut W) -> Result<()>

Writes the chunk to the writer in the Prometheus format.

Trait Implementations

impl Debug for Chunk

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

Formats the value using the given formatter.

impl PartialEq for Chunk

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