Function estimateStringFixedTransformCost

ext/strings.go:904–910

Cost estimation functions for string extensions. These functions provide compile-time cost estimates proportional to the size of the input string(s), ensuring that the CEL cost system accurately reflects the computational work performed by string operations. estimateStringFixedTransformCost estimat
