valueint :: Int -> Builder

valueint32 :: Int32 -> Builder

valueint64 :: Int64 -> Builder

valueword16 :: Word16 -> Builder

Source#

Note: This results in a zigzag encoded number. Avro does not have unsigned types.

valueword32 :: Word32 -> Builder

Source#

Note: This results in a zigzag encoded number. Avro does not have unsigned types.

valueword128 :: Word128 -> Builder

Source#

Note: This results in a fixed encoded value of length 16. In the schema, the type must be {"type": "fixed", "name": "...", "size": 16}. A big-endian encoding is used.

valuebytes :: Bytes -> Builder

valuechunks :: Chunks -> Builder

Encode a map with exactly two key-value pairs. The keys are text. This is commonly used to encode the header in an avro file, which has a map with two keys: avro.schema and avro.codec.
