Detailed Description

template<typename CP32, typename Range>
class U_HEADER_ONLY_NAMESPACE::UnsafeUTFStringCodePoints< CP32, Range >

A C++ "range" for non-validating iteration over all of the code points of a code unit range.

The string must be well-formed.

Call unsafeUTFStringCodePoints() to have the compiler deduce the Range type.

Template Parameters

CP32	Code point type: UChar32 (=int32_t) or char32_t or uint32_t
Range	A C++ "range" of Unicode UTF-8/16/32 code units

U_HEADER_ONLY_NAMESPACE::UnsafeUTFStringCodePoints< CP32, Range >::UnsafeUTFStringCodePoints ( Range  unitRange )

inlineexplicit

Constructs a C++ "range" object over the code points in the string.

Parameters

unitRange

input range

UnsafeUTFStringCodePoints() [3/4]

template<typename CP32 , typename Range >

template<typename R = Range, typename = std::enable_if_t<std::is_reference_v<R>>, typename = void>

U_HEADER_ONLY_NAMESPACE::UnsafeUTFStringCodePoints< CP32, Range >::UnsafeUTFStringCodePoints ( Range  unitRange )

inlineexplicit

Constructs a C++ "range" object over the code points in the string, keeping a reference to the code unit range.

This overload is used by utfStringCodePoints in C++17; in C++20, a ref_view is used instead (via views::all).

Parameters

unitRange

input range
