void VectorView<E> ()Defined at line 52 of file ../../sdk/lib/fidl/cpp/wire/include/lib/fidl/cpp/wire/vector_view.h
void VectorView<E> (AnyArena & allocator, size_t size)Allocates a vector using an arena. |T| is default constructed.

template <typename InputIterator>void VectorView<E> (AnyArena & arena, InputIterator first, InputIterator last)Allocates a vector using an arena and copies the data from the supplied iterators.
The iterator must satisfy the random_access_iterator concept.
Example:
fidl::Arena arena;
std::vector
<int32
_t> vec(...);
// Copy contents of |vec| into |arena|, and return a view of the copies content.
fidl::VectorView
<int32
_t> vv(arena, vec.begin(), vec.end());

void VectorView<E> (AnyArena & arena, cpp20::span<const T> span)Allocates a vector using an arena and copies the data from the supplied |span|.

void VectorView<E> (AnyArena & arena, cpp20::span<const T> span)Allocates a vector using an arena and copies the data from the supplied |span|.

VectorView<T> FromExternal (std::vector<std::remove_cv_t<T>> & from)Constructs a fidl::VectorView by unsafely borrowing other sequences.
|FromExternal| methods are the only way to reference data which is not
managed by an arena. Their usage is discouraged. The lifetime of the
referenced vector must be longer than the lifetime of the created
|VectorView|.
For example:
std::vector
<int32
_t> my_vector = { 1, 2, 3 };
auto my_view =
fidl::VectorView
<int32
_t>::FromExternal(my_vector);

size_t count ()Deprecated in favor of `size()`.
The Banjo convention was to use `count()` to express quantities of
elements, and use `size()` to express quantities of bytes. This method
facilitates migrating from Banjo to FIDL.

void set_count (size_t size)Deprecated in favor of `set_size()`. See `count()` for historical context.

is absent. This can be removed if optional view types switch to
|fidl::WireOptional|.
