Macro optimize_split 

optimize_split!() { /* proc-macro */ }

Analyze string patterns at compile time and generate optimized split code.

This macro examines delimiter patterns and input characteristics to select the most efficient splitting strategy at compile time.

Examples

// Simple comma splitting - generates optimized code
let result = optimize_split!("field1,field2,field3", ",");
 
// Multiple delimiters - generates multi-delimiter optimization
let result = optimize_split!(input_str, [",", ";", ":"]);
 
// Complex patterns - generates pattern-specific optimization
let result = optimize_split!(data, [",", "->", "::"], preserve_delimiters = true);

Debug Attribute

The debug attribute enables diagnostic output for macro expansion:

#[ optimize_split( debug ) ]
let result = optimize_split!(input, ",");
