pack (or unpack) a list of bytes into a strict or lazy ByteString.

pack x ≡ x '^.' packedBytes
unpack x ≡ x '^.' from packedBytes
packedBytes ≡ from unpackedBytes

pack (or unpack) a list of characters into a strict or lazy ByteString.

When writing back to the ByteString it is assumed that every Char lies between '\x00' and '\xff'.

pack x ≡ x '^.' packedChars
unpack x ≡ x '^.' from packedChars
packedChars ≡ from unpackedChars

Traverse each Word8 in a strict or lazy ByteString

This Traversal walks each strict ByteString chunk in a tree-like fashion enable zippers to seek to locations more quickly and accelerate many monoidal queries, but up to associativity (and constant factors) it is equivalent to the much slower:

bytes ≡ unpackedBytes . traversed

anyOf bytes (== 0x80) :: ByteString -> Bool

Traverse the individual bytes in a strict or lazy ByteString as characters.

When writing back to the ByteString it is assumed that every Char lies between '\x00' and '\xff'.

This Traversal walks each strict ByteString chunk in a tree-like fashion enable zippers to seek to locations more quickly and accelerate many monoidal queries, but up to associativity (and constant factors) it is equivalent to the much slower:

chars ≡ unpackedChars . traversed

anyOf chars (== 'c') :: ByteString -> Bool
