nonblocking-logger 0.3.0

/// Macros for convenient logging with string formatting support
///
/// These macros provide a convenient way to log messages with format string support,
/// similar to the standard library's `println!` macro family.
///
/// # Examples
///
/// ```rust
/// use nonblocking_logger::{info, debug, error};
///
/// fn main() {
///     let user_id = 42;
///     let status = "active";
///     
///     // Simple string
///     info!("User logged in");
///     
///     // With formatting
///     info!("User {} has status: {}", user_id, status);
///     
///     // With debug formatting
///     debug!("Debug info: {:?}", vec![1, 2, 3]);
///     
///     // Error with formatting
///     error!("Failed to process user {}: {}", user_id, "connection timeout");
/// }
/// ```

/// Log a message using format string syntax (always outputs, no level filtering)
///
/// # Examples
///
/// ```rust
/// use nonblocking_logger::log;
///
/// fn main() {
///     let count = 5;
///     
///     // Using global logger
///     log!("Processing {} items", count);
