wirefox

Wirefox is a modern, safe, and fast protobuf library written in Rust that aims to have feature parity with the official google libraries. The minimum supported rust version is 1.91.0.

Planned features (work in progress!)

• proto2, proto3, editions
• zero-copy with copy-on-write data structures
• extensions, groups, message set
• lazy messages
• proto3 json mapping
• reflection
• unknown fields
• text formatting

Basic Usage

Wirefox recommends an up-to-date protobuf-compiler installation. The version that comes with some package managers may be outdated. See https://protobuf.dev/installation for instructions on how to install it.

Differences in behavior from the official documented limits and the c++ library

• an unknown proto2 enum is not truncated to 32 bits in the unknown fields ^{[14] [18]}
• an unknown wire type is handled as an error before field number zero ^{[11] [19]}
• buffers longer than i32::MAX are valid ^[16]
• the default recursion limit is 128 ^{[17] [20]}
• an unknown map entry's data is stored verbatim ^{[21] [22]}
