Must accepts dual paramater returns with an error on the end. This function returns the resulting object if the error returned in nil. This function will panic if the error is not nil.

Types

type Matcher

type Matcher string

Matcher is an alias of a string that can contain specific variable instructsions to be replaced when calling the 'String' function. This alias provides the 'Match' function, which returns a Regexp struct that will match any value generated.

func (Matcher) Match

func (s Matcher) Match() Regexp

Match returns a valid Regexp struct that is guaranteed to match any string generated by the Matcher's 'String' function.

func (Matcher) MatchEx

func (s Matcher) MatchEx(o bool) Regexp

MatchEx returns a valid Regexp struct that is guaranteed to match any string generated by the Matcher's 'String' function. MatchEx returns an inverse matcher if the bool is false

func (Matcher) String

func (s Matcher) String() string

String parses this MatchString value and will preform any replacements and fill any variables contained.

func (Matcher) UnMatch

func (s Matcher) UnMatch() Regexp

UnMatch returns a valid Regexp struct that is guaranteed to not match any string generated by the Matcher's 'String' function.

type Regexp

type Regexp interface {
	String() string
	Match([]byte) bool
	MatchString(string) bool
}

Regexp is a compatibility interface that is used to allow for UnMatch values to be used lacking the ability of RE2 used in Golang to do negative lookahead.

type String

type String string

String is a wrapper for strings to support the fmt.Stringer interface.

func (String) String

func (s String) String() string

String returns the string value of itself.
