Description

This module provides the Mac data type and functions for working with it.

Synopsis

Convert

mac :: Word64 -> Mac Source #

Construct a Mac address from a Word64. Only the lower 48 bits are used.

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)

builderUtf8 :: Mac -> Builder Source #

Make a bytestring builder from a Mac address using a colon as the separator.

parserUtf8 :: Parser Mac Source #

parserWithUtf8 :: MacCodec -> Parser Mac Source #

Parser for a Mac address using the provided settings.

ByteString

decodeBytes :: ByteString -> Maybe Mac Source #

Deprecated: Prefer decodeOctets

This function is deprecated. It will be renamed in a future release since the name is misleading.

UTF-8 Bytes

boundedBuilderUtf8 :: Mac -> Builder 17 Source #

Encode a Mac address as colon-separated hexadecimal octets, preferring lowercase for alphabetical characters.

>>> BBB.run Nat.constant $ boundedBuilderUtf8 $ mac 0xDEADBEEF1609
[0x64, 0x65, 0x3a, 0x61, 0x64, 0x3a, 0x62, 0x65, 0x3a, 0x65, 0x66, 0x3a, 0x31, 0x36, 0x3a, 0x30, 0x39]

decodeUtf8Bytes :: Bytes -> Maybe Mac Source #

Lenient decoding of MAC address. This is case insensitive and allows either : or - as the separator. It also allows leading zeroes to be missing.

>>> decodeUtf8Bytes (Bytes.fromAsciiString "A2:DE:AD:BE:EF:67")
Just (mac 0xa2deadbeef67)
>>> decodeUtf8Bytes (Bytes.fromAsciiString "13-a2-FE-A4-17-96")
Just (mac 0x13a2fea41796)

parserUtf8Bytes :: e -> Parser e s Mac Source #

Leniently parse UTF-8-encoded Bytes as a Mac address. This is case insensitive and allows either : or - as the separator. It also allows leading zeroes to be missing.

>>> Parser.parseBytes (parserUtf8Bytes ()) (Bytes.fromAsciiString "de:ad:BE:EF:1:23")
Success (Slice {offset = 16, length = 0, value = mac 0xdeadbeef0123})

Printing

print :: Mac -> IO () Source #

Print a Mac address using the textual encoding.

Types

newtype Mac Source #

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.

Methods

rnf :: Mac -> () #

Prim Mac Source #

This only preserves the lower 6 bytes of the 8-byte word that backs a mac address. It runs slower than it would if it used a full 8-byte word, but it consumes less space. When storing millions of mac addresses, this is a good trade to make. When storing a small number of mac address, it might be preferable to make a primitive array of Word64 instead and use the mac address data constructor to coerce between the two.

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.
