Public predicates

parse/2

Parses Avro binary data from the given source (bytes(List), stream(Stream), or file(Path)) returning a Schema-Data pair. When the schema is not present in the file, Schema is unified with false.

Compilation flags:

static

Template:

parse(Source,Schema-Data)

Mode and number of proofs:

parse(++compound,--pair) - one_or_error

---

parse/3

Parses Avro binary data from the given source using the provided schema, returning the decoded data.

Compilation flags:

static

Template:

parse(Source,Schema,Data)

Mode and number of proofs:

parse(++compound,++term,--term) - one_or_error

---

generate/3

Generates Avro binary data to the given sink (bytes(List), stream(Stream), or file(Path)) from the given schema and data. The schema is not included in the output.

Compilation flags:

static

Template:

generate(Sink,Schema,Data)

Mode and number of proofs:

generate(++compound,++term,++term) - one_or_error

---

generate/4

Generates Avro binary data to the given sink from the given schema and data. When IncludeSchema is true, generates an Avro Object Container File with the schema embedded.

Compilation flags:

static

Template:

generate(Sink,IncludeSchema,Schema,Data)

Mode and number of proofs:

generate(++compound,++boolean,++term,++term) - one_or_error
