moosicbox_assert 0.2.0

//! Environment-controlled assertion macros for conditional debugging and testing.
//!
//! This crate provides assertion macros that can be toggled at runtime via the `ENABLE_ASSERT`
//! environment variable. When enabled, failed assertions exit the process with colorized error
//! messages and backtraces. When disabled, the macros have varying fallback behaviors:
//! returning errors, logging warnings, panicking, or becoming no-ops.
//!
//! # Use Cases
//!
//! * Development and debugging environments where you want strict checking
//! * Production environments where you want graceful degradation instead of process termination
//! * Testing scenarios where you need conditional assertion behavior
//! * Gradual migration from development assertions to production error handling
//!
//! # Environment Variables
//!
//! * `ENABLE_ASSERT` - Set to "1" to enable strict assertion mode (process exits on failure),
//!   any other value uses the fallback behavior of each macro
//!
//! # Examples
//!
//! Basic assertion that exits when enabled, does nothing when disabled:
//!
//! ```rust,no_run
//! use moosicbox_assert::assert;
//!
//! unsafe { std::env::set_var("ENABLE_ASSERT", "1"); }
//! let value = 42;
//! assert!(value > 0, "Value must be positive");
//! ```
//!
//! Assertion that returns an error when disabled:
//!
//! ```rust,no_run
//! use moosicbox_assert::assert_or_err;
//!
//! #[derive(Debug)]
//! enum Error { Invalid }
//!
//! fn validate(x: i32) -> Result<(), Error> {
//!     assert_or_err!(x >= 0, Error::Invalid, "Value must be non-negative");
//!     Ok(())
//! }
//! ```
//!
//! # Available Macros
//!
//! * [`assert!`] - Conditional assertion that exits or does nothing
//! * [`assert_or_err!`] - Returns an error when disabled
//! * [`assert_or_error!`] - Logs an error when disabled
//! * [`assert_or_panic!`] - Panics when disabled
//! * [`assert_or_unimplemented!`] - Calls `unimplemented!()` when disabled
//! * [`die!`] - Unconditional exit when enabled, no-op when disabled
//! * [`die_or_err!`] - Returns an error when disabled
//! * [`die_or_error!`] - Logs an error when disabled
//! * [`die_or_warn!`] - Logs a warning when disabled
//! * [`die_or_panic!`] - Panics when disabled
//! * [`die_or_propagate!`] - Propagates errors using `?` when disabled
//! * [`die_or_unimplemented!`] - Calls `unimplemented!()` when disabled
