protobuf

Description

The egg provides facilities to read and write Protocol Buffers in binary format and comes with a plug-in for the protoc compiler that generates CHICKEN code from a .proto definition file.

Programming Interface

Most of the time you will run protoc --chicken_out=... on your definition files and import only the generated modules plus the protobuf module from the protobuf library into your code. The generated modules contain SRFI-99 record types for every protocol buffer message type and reflection information used by the (de-)serialization process for every protocol buffer message or enumeration type.

The protobuf library also contains additional modules that allow you to hook into the protocol buffer (de-)serialization process or perform low-level manipulations of the wire format manually.

protobuf

This module contains the high-level entry points for protocol buffer (de-)serialization and re-exports message?, message-extensions and message-unknown from the protobuf-reflection module.

[procedure] (deserialize TYPE [PORT])

Deserializes a binary protocol buffer stream from PORT (or (current-input-port)) into a record of the given TYPE, which must be the SRFI-99 record type descriptor of a protocol buffer message type.

[procedure] (serialize MSG [PORT])

Serializes the protocol buffer message MSG to the PORT (or (current-output-port)) as a binary protocol buffer stream. MSG must be a SRFI-99 record instance of a protocol buffer message type.
