exomonad-core 0.1.0

//! Logging utilities for exomonad.

//! Provides a standardized way to initialize tracing across all exomonad binaries.

///
/// - Uses `RUST_LOG` environment variable for filtering.
/// - Outputs to `stderr` to avoid corrupting `stdout` (useful for JSON output).
/// - Disables target display for cleaner CLI output.
