C string safety library in D

libcstring

Library written in D for handling C strings.

This library is mainly made to interface with C libraries or to use strings in a C-like manner without the mental burden of making sure strings fit, etc.

This library is:

• @safe
• @nogc
• nothrow
• meant for baremetal
• compatible with OpenD
• compatible with BetterC (unittests are not)
• based on Meta's Folly fbstring library

This library is NOT:

• faster than native D GC strings always -- more below
• smaller than native D GC strings -- 16 bytes vs 32 bytes
• a drop-in replacement for anything

This library should really only be used in embedded or baremetal environments where programmers are worried about C string semantics (as they use C linkage) but want to have a string that is basically equivalent to what they would have written, albeit more correct. No longer do you need to struggle with strcat or strncat in C; you can create an object and use .cat()! It may also be faster depending on how your C string was allocated, as this library allocates memory eagerly, meaning most times there is no need for a reallocation when concatenating two strings. If you have the memory to spare, this is an excellent and easy-to-use string library for C strings.
