Builder for Labels

Implementations§

source§

impl LabelsBuilder

source

pub fn new(names: Vec<&str>) -> LabelsBuilder

Create a new empty LabelsBuilder with the given names

source

pub fn reserve(&mut self, additional: usize)

Reserve space for additional other entries in the labels.

source

pub fn size(&self) -> usize

Get the number of labels in a single value

source

pub fn add<T>(&mut self, entry: &[T])where T: Copy + Into<LabelValue>,

Add a single entry to this set of labels.

This function will panic when attempting to add the same label more than once.

source

pub fn finish(self) -> Labels

Finish building the Labels
