Available on crate feature prometheus-encoding only.

An interface for encoding metric families into an underlying wire protocol.

Required Methods

fn encode<W>(&self, mfs: &[MetricFamily], writer: &mut W) -> Result<(), Error>where W: Write,

encode converts a slice of MetricFamily proto messages into target format and writes the resulting lines to writer. This function does not perform checks on the content of the metrics and label names, i.e. invalid metrics or label names will result in invalid text format output.

fn format_type(&self) -> &str

format_type returns target format.
