Struct Levels 

pub struct Levels(/* private fields */);

A score rubric: either a plain count or the text of each level.

The conversions exist so .score("sev", "How bad?", 5) and .score("sev", "How bad?", ["low", "high"]) both read naturally at the call site.

Implementations

impl Levels

pub fn count(count: u32) -> Self

A rubric of count generated levels. From<u8> covers a literal at the call site; this takes a count read from somewhere else, so a value too large for any rubric still reaches the service and is refused there with the bounds, rather than wrapping on the way.

pub fn labels<S: AsRef<str>>(labels: impl IntoIterator<Item = S>) -> Self

A rubric from level texts, lowest first.
