internal API for now, subject to modifications and moving around

string API's focusing on performance, that can be used as building blocks for other routines.

Un-necessary allocations are avoided and appropriate algorithms are used at the expense of code clarity when justified.

Procs

proc dataPointer[T](a: T): pointer
same as C++ data that works with std::string, std::vector etc. Note: safe to use when a.len == 0 but whether the result is nil or not is implementation defined for performance reasons.   Source   Edit
proc forceCopy(result: var string; a: string) {....raises: [], tags: [].}
also forces a copy if a is shallow   Source   Edit
proc setLen(result: var string; n: int; isInit: bool) {....raises: [], tags: [].}
when isInit = false, elements are left uninitialized, analog to {.noinit.} else, there are 0-initialized.   Source   Edit
proc toLowerAscii(a: var string) {....raises: [], tags: [].}
optimized and inplace overload of strutils.toLowerAscii   Source   Edit
