# core.stdcpp.string

D header file for interaction with C++ std::string.

enum DefaultConstruct `Default`;
  Constructor argument for default construction
struct `char_traits`(CharT);
  Character traits classes specify character properties and provide specific semantics for certain operations on characters and sequences of characters.
struct `basic_string`(T, Traits = char_traits!T, Alloc = allocator!T);
  D language counterpart to C++ std::basic_string.
  C++ reference:
  enum size_type `npos`;
  alias `size_type` = size_t;
  alias `difference_type` = ptrdiff_t;
  alias `value_type` = T;
  alias `traits_type` = Traits;
  alias `allocator_type` = Alloc;
  alias `pointer` = value_type*;
  alias `const_pointer` = const(value_type)*;
  alias `toString` = as_array;
  this();
    MSVC allocates on default initialisation in debug, which can't be modelled by D struct

  const pure nothrow @safe bool `opEquals`(ref scope const basic_string `s`);
  const pure nothrow @safe bool `opEquals`(scope const T[] `s`);
    Two basic_strings are equal if they represent the same sequence of code units.
  const pure nothrow @safe int `opCmp`(ref scope const basic_string `rhs`);
  const pure nothrow @safe int `opCmp`(scope const T[] `rhs`);
    Performs lexicographical comparison.
  const pure nothrow @nogc @safe size_t `toHash`();
    Hash to allow basic_strings to be used as keys for built-in associative arrays. The result will generally not be the same as C++ std::hash<std::basic_string<T>>.
