Trait prometheus::Encoder [] [src]

pub trait Encoder {
    fn encode<W: Write>(&self, _: &[MetricFamily], _: &mut W) -> Result<()>;
fn format_type(&self) -> &str; }

Encoder types encode metric families into an underlying wire protocol.

Required Methods

encode converts a slice of MetricFamily proto messages into target format and writes the resulting lines to writer. It returns the number of bytes written and any error encountered. This function does not perform checks on the content of the metric and label names, i.e. invalid metric or label names will result in invalid text format output.

format_type returns target format.
