Data.ByteString.Lazy.Internal

A space-efficient representation of a Word8 vector, supporting many efficient operations.

A LazyByteString contains 8-bit bytes, or by using the operations from Data.ByteString.Lazy.Char8 it can be interpreted as containing 8-bit characters.

Type synonym for the lazy flavour of ByteString.

Smart constructor for Chunk. Guarantees the data type invariant.

Consume the chunks of a lazy ByteString with a natural right fold.

Consume the chunks of a lazy ByteString with a strict, tail-recursive, accumulating left fold.

The data type invariant: Every ByteString is either Empty or consists of non-null StrictByteStrings. All functions must preserve this.

Lazily checks that the given ByteString satisfies the data type's "no empty chunks" invariant, raising an exception in place of the first chunk that does not satisfy the invariant.

The chunk size used for I/O. Currently set to 32k, less the memory management overhead

The recommended chunk size. Currently set to 4k, less the memory management overhead

The memory management overhead. Currently this is tuned for GHC only.

O(1) Convert a StrictByteString into a LazyByteString.

O(n) Convert a LazyByteString into a StrictByteString.

Note that this is an expensive operation that forces the whole LazyByteString into memory and then copies all the data. If possible, try to avoid converting back and forth between strict and lazy bytestrings.
