Struct flatdata::MultiArrayView

pub struct MultiArrayView<'a, Ts> where
    Ts: VariadicRefFactory,  { /* fields omitted */ }

A read-only view on a multivector.

For the detailed description of multivector and examples, cf. MultiVector.

Methods

impl<'a, Ts> MultiArrayView<'a, Ts> where
    Ts: VariadicRefFactory, 

pub fn new(
    index: ArrayView<'a, <Ts as VariadicStruct<'a>>::Index>,
    data_mem_descr: &'a [u8]
) -> Self

Creates a new MultiArrayView to the data at the given address.

The returned array view does not own the data.

pub fn len(&self) -> usize

Number of indexed items in the array.

Note that this is not the total number of overall elements stored in the array. An item may be also empty.

pub fn is_empty(&self) -> bool

Returns true if no item is stored in the array.

pub fn at(&self, index: usize) -> MultiArrayViewItemIter<'a, Ts>

Returns a read-only iterator to the elements of the item at position index.

Panics

Panics if index is greater than or equal to MultiArrayView::len().

pub fn slice<R: RangeBounds<usize>>(&self, range: R) -> Self

Slice this array view by a given range.

Panics

Panics if the range is outside of bounds of array view.

pub fn iter(&self) -> MultiArrayViewIter<'a, Ts>

Returns an iterator through the indexed items of the array.

Trait Implementations
