-- | A compact representation of a <a>Word8</a> vector.

--   It is suitable for use as an internal representation for code that

--   be used as an interchange type. That is, it should not generally be

-- | Sequences are defined as Arrays:
--   
--   Array v = A0 | A1 v (Array v) | A2 v v (Array v) ... | A255 ... (Array
--   v)
--   
--   In practice, this means that the sequence is encoded as a sequence of
--   blocks of up to 255 elements, with every block preceded by the count
--   of the elements in the block and a final 0-length block.
--   
--   Lists are defined as:
--   
--   List a ≡ Nil | Cons a (List a)
--   
--   In practice, this means that the list elements will be prefixed with a
--   1 bit and followed by a final 0 bit.
--   
--   The AsList/AsArray wrappers can be used to serialise sequences as
--   Lists or Arrays.
--   
--   Let's see some examples.
--   
--   <pre>
--   &gt;&gt;&gt; flatBits $ AsList [True,True,True]
--   "1111110"
--   </pre>
--   
--   So we have Cons True (11) repeated three times, followed by a final
--   Nil (0).
--   
--   The list encoding is the default one for lists so AsList is in this
--   case unnecessary:
--   
--   <pre>
--   &gt;&gt;&gt; flatBits $ [True,True,True]
--   "1111110"
--   </pre>
--   
--   We can force a list to be encoded as an Array with AsArray:
--   
--   <pre>
--   &gt;&gt;&gt; flatBits $ AsArray [True,True,True]
--   "00000011 11100000 000"
--   </pre>
--   
--   We have the initial block with a count of 3 (3 == 00000011) followed
--   by the elements True True True (111) and then the final block of 0
--   elements ("00000 000").
--   
--   <pre>
--   &gt;&gt;&gt; flatBits $ [AsArray [True,True,True]]
--   "10000001 11110000 00000"

module Flat.Repr

-- | Flat representation of a value
--   
--   <h2>Repr </h2>
--   
--   It is occasionally useful to keep a decoded value, or part of it, in
--   its encoded binary representation and decode it later on demand.
--   
--   To do so, just decode a value <tt>a</tt> to a `Repr a`.
--   
--   For example, we encode a list of Ints and then decode it to a list of
--   Repr Int:
--   
--   <pre>
--   &gt;&gt;&gt; unflat (flat [1::Int .. 5]) :: Decoded ([Repr Int])
--   Right [Repr {repr = "\STX\SOH"},Repr {repr = "\EOT\SOH"},Repr {repr = "\ACK\SOH"},Repr {repr = "\b\SOH"},Repr {repr = "\n\SOH"}]
--   </pre>
--   
--   To decode a `Repr a` to an <tt>a</tt>, we use <a>unrepr</a>:
--   
--   <pre>
--   &gt;&gt;&gt; let Right l = unflat (flat [1..5]) :: Decoded [Repr Int] in unrepr (l  !! 2)
--   3
--   </pre>
--   
--   See "test/FlatRepr.hs" for a test and a longer example of use.
--   
--   <h2>SizeOf</h2>
--   
--   If a decoded value is not required, it can be skipped completely using
--   `SizeOf a`.
--   
--   For example, to ignore the second and fourth component of the
--   following tuple, it can be decoded as:
--   
--   <pre>
--   &gt;&gt;&gt; let v = flat ('a',"abc",'z',True) in unflat v :: Decoded (Char,SizeOf String,Char,SizeOf Bool)
--   Right ('a',SizeOf 28,'z',SizeOf 1)
--   </pre>
--   
--   The unused values have not been decoded and instead their size (in
--   bits) is returned.
