Function googletest::matchers::contains_regex

pub fn contains_regex<ActualT: ?Sized, PatternT: Deref<Target = str>>(
    pattern: PatternT
) -> ContainsRegexMatcher<ActualT>

Matches a string containing a substring which matches the given regular expression.

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

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

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