MakeSpan() [1/3]

template<typename A , int N>

Span<A> constexpr MakeSpan

(

A(&)

a[N]

)

MakeSpan for arrays:

Here is the caller graph for this function:

MakeSpan() [2/3]

template<typename V >

constexpr auto MakeSpan

(

V &&v

SPAN_ATTR_LIFETIMEBOUND

)

-> typename std::enable_if<!std::is_lvalue_reference<V>::value, Span<const typename std::remove_pointer<decltype(v.data())>::type>>::type

MakeSpan for temporaries / rvalue references, only supporting const output.

Definition at line 224 of file span.h.

MakeSpan() [3/3]

template<typename V >

constexpr auto MakeSpan

(

V &v

SPAN_ATTR_LIFETIMEBOUND

)

-> Span<typename std::remove_pointer<decltype(v.data())>::type>

MakeSpan for (lvalue) references, supporting mutable output.

Definition at line 226 of file span.h.

MakeUCharSpan()

template<typename V >

constexpr auto MakeUCharSpan

(

V &&

v

)

-> decltype(UCharSpanCast(MakeSpan(std::forward<V>(v))))

Like MakeSpan, but for (const) unsigned char member types only.

Only works for (un)signed char containers.
