Package `wildcard` provides utils for working with a classic wildcard matching (only `?` and `*` are supported).

`Match` function is a golang's adaptation of [Java's O(1) space solution](https://www.programcreek.com/2014/06/leetcode-wildcard-matching-java/) and ~ 3.37 times faster (76.0ns/22.5ns) then standard `filepath.Match`.

## Example

```go

package main

import (

  "fmt"

  "github.com/iamolegga/wildcard"

)

func main() {

  fmt.Println(wildcard.Match("value", "v?l*"))

  fmt.Println(wildcard.IsPattern("v?l*"))

}

```

## Performance

It was compared with `filepath.Match` function with several runs:

```sh

$ for i in {1..10}; do go test -run=NONE -bench=. ./... >> old.txt; done

$ # change implementation to `filepath.Match`

$ for i in {1..10}; do go test -run=NONE -bench=. ./... >> new.txt; done

$

$ benchstat old.txt new.txt

name     old time/op  new time/op  delta

Match-4  22.5ns ± 2%  76.0ns ±19%  +238.01%  (p=0.000 n=10+10)

```

`old` - current implementation

`new` - utilize `filepath.Match`
