Expand description
An interface for encoding metric families into an underlying wire protocol.
Required Methods§
sourcefn encode<W: Write>(&self, mfs: &[MetricFamily], writer: &mut W) -> Result<()>
fn encode<W: Write>(&self, mfs: &[MetricFamily], writer: &mut W) -> Result<()>
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.
sourcefn format_type(&self) -> &str
fn format_type(&self) -> &str
format_type
returns target format.
