StrInsertManyFast

Description

Fast (order-not-preserving) variant of StrInsertMany. Same shapes as StrInsertMany; the trailing-character preservation is sacrificed for an O(1) at-position write. Use when the relative order of trailing characters after the insertion is irrelevant.

Success

Returns true; bytes copied at idx; characters at and after idx are moved to the new tail (order not preserved).

Failure

Returns false on allocation failure. str unchanged.
