macro_rules! msg_debug {
($msg:expr) => { ... };
}Expand description
Debug-only message display with ๐ prefix.
This macro provides debug-specific logging that only appears when debug mode is explicitly enabled. Debug messages are useful for troubleshooting and development but are hidden from normal users to avoid clutter.
ยงDebug-Only Behavior
- Debug Mode: Messages are displayed using
tracing::debug! - Normal Mode: Messages are completely suppressed (no output)
- Performance: No overhead in production builds when debug is disabled
ยงVisual Design
- Prefix: ๐ (magnifying glass emoji)
- Purpose: Development and troubleshooting information
- Audience: Developers and power users debugging issues
ยงDebug Message Categories
Debug messages are appropriate for:
- Technical Details: Low-level system information
- State Changes: Internal state transitions and updates
- Performance Metrics: Timing and performance measurements
- Data Flow: How data moves through the system
- Error Context: Additional context for debugging errors
ยงUsage Patterns
ยงTechnical Debug Information
use kasl::msg_debug;
let task_id = 42;
msg_debug!(format!("Processing task with ID: {}", task_id));
// Debug mode output: "๐ Processing task with ID: 42"
// Normal mode output: (nothing)ยงState Change Debugging
use kasl::msg_debug;
let old_state = "Active";
let new_state = "InPause";
msg_debug!(format!("State transition: {:?} -> {:?}", old_state, new_state));
// Debug mode output: "๐ State transition: Active -> InPause"
// Normal mode output: (nothing)
