Module macros 

Macros for structured logging and telemetry.

This module provides convenient macros for creating spans, adding events, and logging messages with various severity levels. The macros provide a more ergonomic interface compared to the lower-level functions and handle attribute creation automatically.

Span Creation

• span!: Creates a new span with optional attributes
• event!: Adds an event to the current span

Logging Macros

• log!: Generic logging macro that accepts a severity level
• trace!: Logs trace-level messages (most verbose)
• debug!: Logs debug-level messages
• info!: Logs informational messages
• warn!: Logs warning messages
• error!: Logs error messages
• fatal!: Logs fatal error messages

Attribute Handling

• attributes!: Creates a slice of key-value attributes
• attribute!: Creates a single key-value attribute

All macros support flexible attribute syntax for adding contextual information.
