Types

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

Parser parses samples from a byte slice of samples in the official Prometheus text exposition format.

func New

func New(b []byte) *Parser

New returns a new parser of the byte slice.

func (*Parser) At

func (p *Parser) At() ([]byte, *int64, float64)

At returns the bytes of the metric, the timestamp if set, and the value of the current sample.

func (*Parser) Err

func (p *Parser) Err() error

Err returns the current error.

func (*Parser) Metric

func (p *Parser) Metric(l *labels.Labels) string

Metric writes the labels of the current sample into the passed labels. It returns the string from which the metric was parsed.

func (*Parser) Next

func (p *Parser) Next() bool

Next advances the parser to the next sample. It returns false if no more samples were read or an error occurred.
