warning: type qualifiers ignored on function return type [-Wignored-qualifiers]

[noiasca]

The library produces two warnings with Arduino UNO in Arduino IDE 1.8.19

`C:\Daten\myrepository\Arduino\libraries\PString/PString.h:56:10: warning: type qualifiers ignored on function return type [-Wignored-qualifiers]
inline const size_t length()
^~~~~

C:\Daten\myrepository\Arduino\libraries\PString/PString.h:60:10: warning: type qualifiers ignored on function return type [-Wignored-qualifiers]
inline const size_t capacity()
^~~~~
`

As code you can use the example test_pstring

According https://stackoverflow.com/questions/1134237/pedantic-gcc-warning-type-qualifiers-on-function-return-type a return type should not be const as the return value can be dynamic. At least for length() this makes sense.

Issue could be solved when keyword const gets removed.
