func NewCatalogFromFSWithMatchFunc

func NewCatalogFromFSWithMatchFunc(db_fs fs.FS, match_func MatchFunc) (map[string]tilepack.MbtilesReader, error)

NewCatalogFromFS return a lookup table of tilepack.MbtilesReader instances from a fs.FS instance whose children return true when compared against the MatchFunction defined in 'match_func'

func NewCatalogFromFSWithRegexp

func NewCatalogFromFSWithRegexp(db_fs fs.FS, re *regexp.Regexp) (map[string]tilepack.MbtilesReader, error)
