func (*FastID) GetTime 

func (c *FastID) GetTime(id int64) int64

func (*FastID) NextID 

func (c *FastID) NextID() int64

type HashID added in v0.0.2 

type HashID struct {
	// contains filtered or unexported fields
}

HashID contains everything needed to encode/decode hashids

func New added in v0.0.2 

func New() (*HashID, error)

New creates a new HashID

func NewWithData added in v0.0.2 

func NewWithData(data *HashIDData) (*HashID, error)

NewWithData creates a new HashID with the provided HashIDData

func (*HashID) Decode added in v0.0.2 

func (h *HashID) Decode(hash string) []int

DEPRECATED: Use DecodeWithError instead Decode unhashes the string passed to an array of int. It is symmetric with Encode if the Alphabet and Salt are the same ones which were used to hash. MinLength has no effect on Decode.

func (*HashID) DecodeHex added in v0.0.2 

func (h *HashID) DecodeHex(hash string) (string, error)

DecodeHex unhashes the string passed to a hexadecimal string. It is symmetric with EncodeHex if the Alphabet and Salt are the same ones which were used to hash.

Each hex nibble is decoded from an integer in range [16, 31].

func (*HashID) DecodeInt64 added in v0.0.2 

func (h *HashID) DecodeInt64(hash string) []int64

DEPRECATED: Use DecodeInt64WithError instead DecodeInt64 unhashes the string passed to an array of int64. It is symmetric with EncodeInt64 if the Alphabet and Salt are the same ones which were used to hash. MinLength has no effect on DecodeInt64.

func (*HashID) DecodeInt64WithError added in v0.0.2 

func (h *HashID) DecodeInt64WithError(hash string) ([]int64, error)

DecodeInt64 unhashes the string passed to an array of int64. It is symmetric with EncodeInt64 if the Alphabet and Salt are the same ones which were used to hash. MinLength has no effect on DecodeInt64.

func (*HashID) DecodeWithError added in v0.0.2 

func (h *HashID) DecodeWithError(hash string) ([]int, error)

Decode unhashes the string passed to an array of int. It is symmetric with Encode if the Alphabet and Salt are the same ones which were used to hash. MinLength has no effect on Decode.

func (*HashID) Encode added in v0.0.2 

func (h *HashID) Encode(numbers []int) (string, error)

Encode hashes an array of int to a string containing at least MinLength characters taken from the Alphabet. Use Decode using the same Alphabet and Salt to get back the array of int.

func (*HashID) EncodeHex added in v0.0.2 

func (h *HashID) EncodeHex(hex string) (string, error)

EncodeHex hashes a hexadecimal string to a string containing at least MinLength characters taken from the Alphabet. A hexadecimal string should not contain the 0x prefix. Use DecodeHex using the same Alphabet and Salt to get back the hexadecimal string.

Each hex nibble is encoded as an integer in range [16, 31].

func (*HashID) EncodeInt64 added in v0.0.2 

func (h *HashID) EncodeInt64(numbers []int64) (string, error)

EncodeInt64 hashes an array of int64 to a string containing at least MinLength characters taken from the Alphabet. Use DecodeInt64 using the same Alphabet and Salt to get back the array of int64.

type HashIDData added in v0.0.2 

type HashIDData struct {
	// Alphabet is the alphabet used to generate new ids
	Alphabet string

	// MinLength is the minimum length of a generated id
	MinLength int

	// Salt is the secret used to make the generated id harder to guess
	Salt string
}

HashIDData contains the information needed to generate hashids

func NewData added in v0.0.2 

func NewData() *HashIDData

NewData creates a new HashIDData with the DefaultAlphabet already set.
