# SCRU128: Sortable, Clock and Random number-based Unique identifier

SCRU128 ID is a supersede [UUID] that has the following features:

- 128-bit unsigned integer type

- Sortable by generation time (as integer and as text)

- 25-digit case-insensitive textual representation (Base36)

- 48-bit millisecond Unix timestamp that ensures useful life until year 10889

- Up to 281 trillion time-ordered but unpredictable unique IDs per millisecond

- 80-bit three-layer randomness for global uniqueness

```julia

julia> using SCRU128

julia> id = SCRU128Id()

SCRU128Id(0x0180cf01d7e41f149affea220e4508d2)

julia> string(id) # convert id to string

"037BY37CNY3426KUV0W41B0LU"

julia> UInt128(id) # conver id to UInt128

0x0180cf01d7e41f149affea220e4508d2

julia> string.(Iterators.take(scru128(), 5)) # using generator

5-element Vector{String}:
