Network.Solana.Core.Compact

Solana serializes lengths as compact-u16: a Word16 packed into 1–3 bytes, little-endian, 7 data bits per byte, with the high bit of each byte flagging a continuation byte. The third byte may only carry 2 data bits, and aliased (non-canonical) encodings are rejected when decoding. A CompactArray is a sequence serialized as its compact-u16 length followed by the serialized items.

valuegetCompactU16 :: Get Word16

Decode a compact-u16 value. Fails on encodings longer than 3 bytes, on aliased (non-canonical) encodings, on an invalid third byte, and on values exceeding Word16.

valueputCompactU16 :: Word16 -> Put

Encode a Word16 as compact-u16 (1–3 bytes).

valueencodeCompactU16 :: Word16 -> ByteString

Run putCompactU16 to a lazy byte string.

valuedecodeCompactU16 :: ByteString -> Either String Word16

Run getCompactU16 over a lazy byte string, returning the decoder's error message on failure.

datadata CompactArray a

A list paired with its length, serialized (Binary put) as a compact-u16 length prefix followed by each item. Build with mkCompact.

valuemkCompact :: [a] -> CompactArray a

Wrap a list into a CompactArray, recording its length. The length is truncated to Word16.

valueunCompact :: CompactArray a -> [a]

The items of the array.

valuegetCompactArrayLength :: CompactArray a -> Word16

The recorded number of items.
