//! Logging targets allow filtering of log messages by their source. By default, the log crate sets
//! the target to the module path where the log macro was invoked if no target is provided.
//!
//! These macros essentially disable using the default target and instead require the target to be
//! explicitly set. This is to avoid implicit pooling of log messages under the same default target,
//! which can make it difficult to filter log messages by their source.
