⚡️ Speed up RowSplitter.get_tree_icon() by 21% in rich/layout.py

[codeflash-ai]

📄 RowSplitter.get_tree_icon() in rich/layout.py

📈 Performance improved by 21% (0.21x faster)

⏱️ Runtime went down from 5.70 microseconds to 4.70 microseconds

Explanation and details

This class method appears simple and does not perform any complex computations or memory-intensive operations. Therefore, there is little to optimize in its runtime or memory usage. However, I can make a small adjustment by ensuring that the method is defined as a static method since it does not use any instance-specific behavior. This could provide a very slight improvement in efficiency by not requiring an instance of the class to call the method.

Here's the optimized version of your program.

This change emphasizes that get_tree_icon does not rely on instance or class-specific data and can be called on the class itself without an instance, potentially optimizing its access slightly.

Correctness verification

The new optimized code was tested for correctness. The results are listed below.
