truffle-sidecar

Provides the truffle mesh networking sidecar binary.

This crate downloads the platform-specific Go sidecar binary at build time from truffle's GitHub releases. The binary is required by truffle-core to establish Tailscale mesh connections.

Usage

use truffle_sidecar::sidecar_path;

let path = sidecar_path();
println!("Sidecar at: {}", path.display());

Override

Set TRUFFLE_SIDECAR_PATH environment variable at build time or runtime to use a custom sidecar binary:

TRUFFLE_SIDECAR_PATH=/usr/local/bin/sidecar-slim cargo build

Set TRUFFLE_SIDECAR_SKIP_DOWNLOAD=1 to skip the build-time download (useful in CI where the sidecar is provided separately).
