# Debug only printing macros for testing This module provides macros for conditional debug printing. These macros only output content during debug builds (e.g., when running `cargo build` or `cargo run`). In release builds (e.g., `cargo build --release` or `cargo run --release`), the print statements are completely omitted by the compiler, ensuring no performance overhead or unnecessary output in production. This is useful for debugging purposes, such as logging intermediate values or states during development, without affecting the final release binary. ## Usage - Use `dprint!` and `dprintln!` for standard output (stdout). - Use `deprint!` and `deprintln!` for standard error (stderr). These macros support the same formatting syntax as Rust's built-in `print!`, `println!`, `eprint!`, and `eprintln!` macros. ## Example ```rust dprintln!("This will only print in debug mode: {}", some_value); deprint!("Error-like message to stderr in debug: {}", error_code); ``` Note: These macros rely on the `#[cfg(debug_assertions)]` attribute, which is enabled by default in debug builds and disabled in release builds.
