Struct Ceiling 

pub struct Ceiling { /* private fields */ }

One limit check measures a result against, and the sentence it produces when the result exceeds it.

check had four of these written out in full, differing only in what they counted and how the number reads – a group count as an integer, a duplicated-line share to one decimal place. Four copies of one shape is how a function acquires branches it does not need.

Implementations

impl Ceiling

pub fn count(limit: Option<usize>, actual: usize, subject: &'static str) -> Self

A ceiling on a number of groups.

pub fn percent( limit: Option<Threshold>, actual: f64, subject: &'static str, ) -> Self

A ceiling on a share of duplicated lines.

pub fn breach(&self) -> Option<String>

What to say when the ceiling is exceeded, and None when it is not.

An unset limit is not a ceiling of zero. It means the caller did not ask, so nothing can breach it.
