Types

type Filter

type Filter interface {
	Match(string) bool
}

func Compile

func Compile(filters []string, separators ...rune) (Filter, error)

Compile takes a list of string filters and returns a Filter interface for matching a given string against the filter list. The filter list supports glob matching with separators too, ie:

f, _ := Compile([]string{"cpu", "mem", "net*"})
f.Match("cpu")     // true
f.Match("network") // true
f.Match("memory")  // false

separators are only to be used for globbing filters, ie:

f, _ := Compile([]string{"cpu.*.count"}, '.')
f.Match("cpu.count")     // false
f.Match("cpu.measurement.count") // true
f.Match("cpu.field.measurement.count")  // false

Compile will return nil if the filter list is empty.

func MustCompile

	// contains filtered or unexported fields
}
