# case-sensitive
22 # (base62) 22
24 # (base62) 7-7-8
# case-insensitive
25 # (base36) 25
29 # (base36) 5-5-5-5-5
32 # (base16) 32

UUID4.uuid_parse — Function
uuid_parse(str::AbstractString; fmt::Int = ncodeunits(str)) -> Tuple{Int, UUID}
source
UUID4.uuid_string — Function
uuid_string(id::UUID = uuid()) -> Dict{Int, String}
uuid_string(id::UUID = uuid(), T) -> T{Int, String} where T <: AbstractDict
