Instance Method Detail
def compatible?(string : String, charset = CHARSET_DEFAULT) : Bool
#
Checks whether a string is base62-compatible.
Base62.compatible?("15Ew2nYeRDscBipuJicYjl970D1") # => true
def decode(string : String, charset = CHARSET_DEFAULT) : BigInt
#
Returns the base62-decoded version of string as a BigInt.
Base62.decode("0000000000000000000001LY7VK") # => 1234567890
def encode(number : Int, charset = CHARSET_DEFAULT) : String
#
Returns the base62-encoded version of number as a String.
Base62.encode(1_234_567_890) # => "1LY7VK"
def encode(value : String | Bytes, charset = CHARSET_DEFAULT) : String
#
Returns the base62-encoded version of value as a String.
Base62.encode("\xFF" * 4) # => "4gfFC3"
Base62.encode(Bytes.new(4, 255_u8)) # => "4gfFC3"
