* Made string_span details::string_length() generic
removed overloads & specialized classes
Creating string_spans using `char16_t` and `char32_t` was not possible
without creating new specializations and function overloads.
This patch makes details::string_length() generic removing the need to
extend the overloads and specializations.
* added type aliases for string_span types char16_t and char32_t
* Added char16_t & char32_t overloads for ensure_z
* added string_span tests for char16_T & char32_t
* added zstring type aliases for char16_t & char32_t
* Added tests for char16_t & char31_t zstring and string_span types
* applies clang format to <gsl/string_span>
* Clang format tests/string_span_tests.cpp
* Removed ensure_z() overloads as they don't add functionality.
using the GSL with MSVC 2017 causes the following warning"
`'std::copy_n::_Unchecked_iterators::_Deprecate': Call to 'std::copy_n'`
This patch removes this since the point of this code is to deal with this issue.
not called even by the unit test (it was calling the "container" ctor
instead). I mimicked the constructor taking a non-const std::array to fix
the issue.
* Fixes issue with dereferencing operator issue #491 introduced in PR #513
dereferencing operator added in PR#513 returned a copy of the object
instead of reference to it.
Adding decltype(auto) as return type of operator* fixes this issue.
* added more tests for not_null::operator*
* Restricting usage of owner<T> to pointer types
* Removing an additional type that was created for testing
* Added comment about the new constraint on owner
* Adding dereference operator to not_null
* Removing dereference operator changes for not-null
* Removing dereference operator changes for not-null
* Review comments
Fixes#510.
* Constrain the converting constructor to not participate in overload resolution when IsConst is true, so that it is never a copy constructor.
* Use Default Member Initializers for span_iterator's data members so that the default constructor can be explicitly defaulted.
* Declare all members of span_iterator GSL_NOEXCEPT: they only throw when contract violations throw.
* Don't use & in operator-> since evil types may overload it.
Project files were not following the clang-format style. For people
using IDEs were clang-format is always run after a save this would
cause unwanted changes.
This commit only applies "clang-format -i" to files.
* Add value_type to span
Currently I'm working on project which involves a lot of `span`s and mocking via Google Mock. Unfortunately a lot of standard matchers requires `value_type` type definition inside container which `gsl::span` lacks.
This pull request add `value_type` type definition inside `gsl::span`
* Strip cv from value_type of span and span_iterator
* Added support of not_null<smart_ptr> comparison
* The return type of not_null comparison operators is determined using SFINAE
#474
* tests for gsl::not_null comparison were added
* not_null comparison tests were rewritten to compare pointers to objects located in the same array
* not_null<shared_ptr> comparison was simplified
* initializer_list overload returns by value to avoid lifetime issues
* generic overload uses expression SFINAE to work with any type that has member size() and operator[], which notably includes const/non-const vector and array.
* Add test coverage for const objects, rvalue initializer_lists, and constexpr usage.
Fixes#357.
* Improve const correctness in string_span
* Improve const correctness in bounds_tests.cpp and byte_tests.cpp
* Improve const correctness in span_tests.cpp
* Improve const correctness in utils_tests.cpp
* Use gsl::owner for dynamically allocated memory in string_span_tests.cpp
* Improve const correctness in string_span_tests.cpp
* Improve const correctness for strided_span_tests.cpp
* GSL_LIKELY/_UNLIKELY always contextually convert their argument to bool.
* Add macro GSL_ASSUME(cond) to inform the optimizer that the predicate cond must hold.
* Reimplement Expects & Ensures as expressions for flexibility and correctness. (Think about "if (cond1) Expects(cond2); else goto fail;")
* Expects and Ensures GSL_ASSUME their predicate when GSL_UNENFORCED_ON_CONTRACT_VIOLATION is defined.
* add gsl::not_null operator<<
Hippomocks, which is a popular mocking engine for C++ uses operator<< on pointers and gets confused about gsl::not_null not having this operator.
* Update gsl
* constexpr all the things.
* remove operator=(const T&)
* it leaves *this in an invalid state if ensure_invariant fails
* implicitly converting the T to not_null and then assigning is in every way superior.
* simplify conversion from not_null<U> with constructor delegation.
* remove the converting assignment operator; again let the conversion constructor and self-assignment operator do the work.
* Cover the remaining pointer arithmetic operations as Wakely suggests in issue #447.
* Cleanup not_null conversions from null pointer constants:
* replace constructor that accepts T with constructor template that accepts U convertible to T
* remove deleted constructor that accepts int
* Attempts to initialize with nullptr, 0, 0L, 0LL, etc. all unambiguously select the deleted nullptr_t constructor.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.

#include <gsl/gsl.h>
Updated headers/tests/instructions/cmake build accordingly
This PR should address https://github.com/Microsoft/GSL/issues/277 (less
the renaming of gsl itself)
initializer_list do not have subscript operator, so the generic container overload of gsl::at fails to compile.
This commits adds an overload of gsl::at for initializer_lists, using *(initializer_list::begin()+index) instead of subscript operator
