    Use Cases & Benefits

    • Generates idiomatic Rust code from Protocol Buffers proto2 and proto3 files for serialization and deserialization.
    • Produces simple, readable Rust types with preserved comments and supports no_std environments for embedded or constrained systems.
    • Use for building efficient, type-safe Rust applications that communicate via Protocol Buffers messages.
    • Use for integrating existing Rust types with Protobuf serialization by adding derive macros and field annotations.
    • Use for generating Rust modules organized by Protobuf package specifiers to maintain clean code structure.

    From the README

    prost is a Protocol Buffers implementation for the Rust Language. prost generates simple, idiomatic Rust code from proto2 and proto3 files.

    Compared to other Protocol Buffers implementations, prost

    First, add prost and its public dependencies to your Cargo.toml:

    The recommended way to add .proto compilation to a Cargo project is to use the prost-build library. See the prost-build documentation for more details and examples.

    See the snazzy repository for a simple start-to-finish example.

    prost follows the tokio-rs project's MSRV model and supports 1.82. For more information on the tokio msrv policy you can check it out here
