Convert
fromOctets :: Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Word8 -> Mac Source #
Create a Mac address from six octets.
toOctets :: Mac -> (Word8, Word8, Word8, Word8, Word8, Word8) Source #
Convert a Mac address to the six octets that make it up.
This function and fromOctets are inverses:
m == (let (a,b,c,d,e,f) = toOctets m in fromOctets a b c d e f)
Textual Conversion
Text
encode :: Mac -> Text Source #
Encode a Mac address lowercase hex, separating every two characters
with a colon:
>>>T.putStrLn (encode (Mac 0xA47F247AB423))a4:7f:24:7a:b4:23
UTF-8 ByteString
encodeUtf8 :: Mac -> ByteString Source #
Encode a Mac address, as lowercase hexadecimal digits
separated by a colon:
>>>BC.putStrLn (encodeUtf8 (mac 0x64255A0F2C47))64:25:5a:0f:2c:47
encodeWithUtf8 :: MacCodec -> Mac -> ByteString Source #
decodeUtf8 :: ByteString -> Maybe Mac Source #
Lenient decoding of MAC address that accepts lowercase, uppercase, and any kind separator.
>>>decodeUtf8 "A2:DE:AD:BE:EF:67"Just (mac 0xa2deadbeef67)>>>decodeUtf8 "13-a2-fe-a4-17-96"Just (mac 0x13a2fea41796)>>>decodeUtf8 "0A42.47BA.67C2"Just (mac 0x0a4247ba67c2)
decodeWithUtf8 :: MacCodec -> ByteString -> Maybe Mac Source #
builderUtf8 :: Mac -> Builder Source #
Make a bytestring builder from a Mac address
using a colon as the separator.
parserUtf8 :: Parser Mac Source #
Lenient parser for a Mac address using any character
as the separator and accepting any digit grouping
(i.e. FA:43:B2:C0:0F:99 or A065.647B.87FA).
parserWithUtf8 :: MacCodec -> Parser Mac Source #
Parser for a Mac address using the provided settings.
ByteString
decodeBytes :: ByteString -> Maybe Mac Source #
Decode a Mac address from a ByteString. Each byte is interpreted
as an octet of the Mac address. Consequently, ByteStrings
of length 6 successfully decode, and all other ByteStrings fail
to decode.
>>>decodeBytes (B.pack [0x6B,0x47,0x18,0x90,0x55,0xC3])Just (mac 0x6b47189055c3)>>>decodeBytes (B.replicate 6 0x3A)Just (mac 0x3a3a3a3a3a3a)>>>decodeBytes (B.replicate 7 0x3A)Nothing
Printing
Types
A 48-bit MAC address. Do not use the data constructor for this type. It is not considered part of the stable API, and it allows you to construct invalid MAC addresses.
Constructors
| MacCodec | |
Fields | |
data MacGrouping Source #
The format expected by the mac address parser. The Word8 taken
by some of these constructors is the ascii value of the character
to be used as the separator. This is typically a colon, a hyphen, or
a space character. All decoding functions are case insensitive.
Constructors
| MacGroupingPairs !Char | Two-character groups, |
| MacGroupingTriples !Char | Three-character groups, |
| MacGroupingQuadruples !Char | Four-character groups, |
| MacGroupingNoSeparator | No separator, |
