Install on Linux

Install rustup from the script published at https://rustup.rs:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Open a new shell, or source $HOME/.cargo/env, then check the toolchain:

rustup show
rustc --version
cargo --version

With the toolchain this repository pins, the version commands print:

rustc 1.97.1 (8bab26f4f 2026-07-14)
cargo 1.97.1 (c980f4866 2026-06-30)

A default stable toolchain from rustup is enough for the crates when it is Rust 1.85 or newer. Building this repository selects 1.97.1 through rust-toolchain.toml.

Add the crates:

cargo new ct-log
cd ct-log
cargo add rfc9162@0.10.0

cargo add rfc9162@0.10.0 resolves the published crate and writes it into Cargo.toml. Continue with getting started.

To install the sidecar binary from crates.io:

cargo install rfc9162-log --version 0.10.0 --locked

With no arguments the binary exits 2 and prints:

rfc9162-sidecar: a command is needed
usage: rfc9162-sidecar COMMAND --dir DIR [...]; commands: init sync snapshot history tree diff blob include
