Regex generator panic

[tienvx]

Matchers (pact-js):

'hydra:member': eachLike({
    'family': {
        'pact:matcher:type': 'regex',
        'pact:generator:type': 'Regex',
        regex: '^\/api\/families\/[0-9a-f]{8}(-[0-9a-f]{4}){3}-[0-9a-f]{12}$',
    },
    'gender': {
        'pact:matcher:type': 'regex',
        'pact:generator:type': 'Regex',
        regex: '(male|female|other)',
    }
})

While the generator for the field gender worked, the generator for the field family panic then stop the mock server.

Looks like rand_regex crate does not support anchors in the regex

Returns an error if the Hir object contains anchors (^, $, \A, \z) or word boundary assertions (\b, \B).

I tried remove anchors ^ and $ and it work fine. Should I keep this issue or close it as won't fix?

[rholshausen]

It needs to be fixed, it shouldn't ever just panic
