// Pattern represents a compiled pattern. It is what is returned
|
|
// from calling either the Compile to MustCompile funcs.
|
|
//
|
|
// Pattern provides the Match, FindAndLoad, and MatchNames methods.
|
|
//
|
|
// Example Usage:
|
|
//
|
|
// pattern, err := pathmath.Compile("/users/{user_id}")
|
|
// if nil != err {
|
|
// fmt.Printf("ERROR Compiling: %v\n", err)
|
|
// return
|
|
// }
|
|
//
|
|
// var userId string
|
|
//
|
|
// didMatch, err := pattern.Find("/users/123", userId)
|
|
// if nil != err {
|
|
// fmt.Printf("ERROR Matching: %v\n", err)
|
|
// return
|
|
// }
|
|
//
|
|
// if didMatch {
|
|
// fmt.Printf("user_id = %q\n", userId)
|
|
// } else {
|
|
// fmt.Println("Did not match.")
