Data.Bytes.Builder.Avro

Builders for encoding data with Apache Avro. Most functions in this module are just aliases for other functions. Avro uses zig-zag LEB128 for all integral types.

Documentation

int :: Int -> Builder

int32 :: Int32 -> Builder

int64 :: Int64 -> Builder

word16 :: Word16 -> Builder

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

word32 :: Word32 -> Builder

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

word128 :: Word128 -> Builder

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.

Arguments

:: Text

First key

-> Builder

First value (already encoded)

-> Text

Second key

-> Builder

Second value (already encoded)

-> 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.
