Function matches_regex 

pub fn matches_regex<PatternT: Deref<Target = str>>(
    pattern: PatternT,
) -> MatchesRegexMatcher<PatternT>

Matches a string the entirety of which which matches the given regular expression.

This is similar to contains_regex, except that the match must cover the whole string and not a substring.

Both the actual value and the expected regular expression may be either a String or a string reference.

verify_that!("Some value", matches_regex("S.*e"))?;  // Passes
verify_that!("Another value", matches_regex("Some"))?;   // Fails
verify_that!("Some value", matches_regex("Some"))?;   // Fails
verify_that!("Some value".to_string(), matches_regex(".*v.*e"))?;   // Passes
verify_that!("Some value", matches_regex(".*v.*e".to_string()))?;   // Passes

Panics if the given pattern is not a syntactically valid regular expression.
