Trait TagsProvider

pub trait TagsProvider<S>where
    Self: AsRef<[S]>,
    S: AsRef<str>,
{ }

Expand description

Types that can provide an iterator of tags for a metric.

This is automatically implemented for anything that implements AsRef<[S]> where S: AsRef<str>.

In other words, you can pass a &[&str] (best), Vec<&str>, &[String], Vec<String>, &[Cow<str>], Vec<Cow<str>>, etc.

If you’d like to pass in empty tags, use the EMPTY_TAGS constant.
