Rust

Updated September 13, 2026

kryptic-daemon-client injects your project's secrets into the process environment during development startup. Outside development it is a no-op, and it never panics.

Source: github.com/dev-kryptic/Kryptic.Rust. The crate name is kryptic-daemon-client. The library is named kryptic, so you call kryptic::inject().

Install

# Cargo.toml
[dependencies]
kryptic-daemon-client = "1.0"

Use

fn main() {
    kryptic::inject(); // call before any env reads

    let db_url = std::env::var("DATABASE_URL").ok();
}

inject() returns an InjectResult { injected, skipped, reason }. Existing environment variables are never overwritten.

Behavior

• No-op when RUST_ENV/APP_ENV/ENVIRONMENT/ENV is production, prod, or staging, or when KRYPTIC_DISABLED=true.
• Finds kryptic.json by walking up from the working directory.
• Never overwrites environment variables that are already set.
• macOS/Linux via unix socket, Windows via named pipe.
