data BCOByteArray a Source #
Wrapper for a ByteArray#.
The phantom type tells what elements are stored in the ByteArray#.
Creating a ByteArray# can be achieved using UArray's API,
where the underlying ByteArray# can be unpacked.

data CgBreakInfo Source #
Information about a breakpoint that we know at code-generation time
In order to be used, this needs to be hydrated relative to the current HscEnv by
hydrateCgBreakInfo. Everything here can be fully forced and that's critical for
preventing space leaks (see #22530)

Breakpoint index
emptyModBreaks :: ModBreaks Source #
Construct an empty ModBreaks
data CCostCentre Source #
C CostCentre type
Store elements in a flattened representation.
A FlatBag is a data structure that stores an ordered list of elements
in a flat structure, avoiding the overhead of a linked list.
Use this data structure, if the code requires the following properties:
- Elements are stored in a long-lived object, and benefit from a flattened representation.
- The
FlatBagwill be traversed but not extended or filtered. - The number of elements should be known.
- Sharing of the empty case improves memory behaviour.
A FlagBag aims to have as little overhead as possible to store its elements.
To achieve that, it distinguishes between the empty case, singleton, tuple
and general case.
Thus, we only pay for the additional three words of an Array if we have at least
three elements.

sizeFlatBag :: FlatBag a -> Word Source #
Calculate the size of
fromSizedSeq :: SizedSeq a -> FlatBag a Source #
Convert a SizedSeq into its flattened representation.
A 'FlatBag a' is more memory efficient than '[a]', if no further modification
is necessary.
elemsFlatBag :: FlatBag a -> [a] Source #
Get all elements that are stored in the FlatBag.
