Data family instances
data family NestedCtxt_ blk ∷ (Type → Type) → Type → Type Source #
Context identifying what kind of block we have
In almost all places we will use NestedCtxt rather than NestedCtxt_.
Instances
type RawHeader = AHeader ByteString Source #
Serialisation
byronBlockEncodingOverhead ∷ Word32 Source #
The Byron block encoding overhead size in bytes.
This encompasses the overhead in bytes for everything that is encoded within a Byron block, excluding the actual generalized transactions (transactions, delegation certificates, update votes, and update proposals).
decodeByronBlock ∷ EpochSlots → Decoder s (ByteString → ByronBlock) Source #
Inverse of encodeByronBlock
decodeByronBoundaryBlock ∷ EpochSlots → Decoder s (ByteString → ByronBlock) Source #
Decoder for a boundary Byron block.
PRECONDITION: the ByteString given as argument to the decoder is the
same as the one that is decoded.
This is a wrapper for decCBORABoundaryBlock.
Use decodeByronBlock when you can, this function is provided for use by
the hard-fork combinator.
decodeByronBoundaryHeader ∷ Decoder s (ByteString → RawBoundaryHeader) Source #
Inverse of encodeByronBoundaryHeader
decodeByronRegularBlock ∷ EpochSlots → Decoder s (ByteString → ByronBlock) Source #
Decoder for a regular (non-EBB) Byron block.
PRECONDITION: the ByteString given as argument to the decoder is the
same as the one that is decoded.
This is a wrapper for decCBORABlock.
Use decodeByronBlock when you can, this function is provided for use by
the hard-fork combinator.
decodeByronRegularHeader ∷ EpochSlots → Decoder s (ByteString → RawHeader) Source #
Inverse of encodeByronRegularHeader
encodeByronBlock ∷ ByronBlock → Encoding Source #
Encode a block
Should be backwards compatible with legacy (cardano-sl) nodes.
Implementation note: the decoder uses decCBORABlockOrBoundary, which
has inverse encCBORABlockOrBoundary. This encoder is intended to be
binary compatible with encCBORABlockOrBoundary, but does not use it and
instead takes advantage of the annotations (using encodePreEncoded).
encodeByronBoundaryHeader ∷ RawBoundaryHeader → Encoding Source #
Encodes a raw Byron EBB header without a tag indicating whether it's a regular header or an EBB header.
Uses the annotation, so cheap.
encodeByronRegularHeader ∷ RawHeader → Encoding Source #
Encodes a raw Byron header without a tag indicating whether it's a regular header or an EBB header.
Uses the annotation, so cheap.
Support for on-disk format
byronBinaryBlockInfo ∷ ByronBlock → BinaryBlockInfo Source #
The BinaryBlockInfo of the given ByronBlock.
NOTE: the bytestring obtained by slicing the serialised block using the
header offset and size will correspond to the header annotation, but not
to the serialised header, as we add an envelope (encodeListLen + tag)
around a header in encodeByronHeader. This envelope must thus still be
added to the sliced bytestring before it can be deserialised using
decodeByronHeader.
Unsized header
decodeUnsizedHeader ∷ EpochSlots → Decoder s (ByteString → UnsizedHeader) Source #
Inverse of encodeSizedHeader
dropV1Envelope ∷ ByteString → Except String (SomeSecond (NestedCtxt Header) ByronBlock, ByteString) Source #
Drop the V1 EBB-or-regular-header envelope and reconstruct the context.
Since we don't know the block size, use fakeByronBlockSizeHint.
encodeUnsizedHeader ∷ UnsizedHeader → Encoding Source #
Encode an unsized header
Does not have to backwards compatible with legacy (cardano-sl) nodes
(which never send or store these headers), but should be inverse to
decodeSizedHeader, and moreover uses decCBORABlockOrBoundaryHdr from
cardano-ledger-byron, and so we don't have too much choice in this encoder.
fakeByronBlockSizeHint ∷ SizeInBytes Source #
Fake size (used in compatibility mode)
