Struct flatdata::ArrayView

pub struct ArrayView<'a, T> where
    T: RefFactory,  { /* fields omitted */ }

A read-only view on a contiguous sequence of flatdata structs of the same type T.

The sequence is written using Vector or ExternalVector. For detailed examples see either of the two.

An archive provides a getter for each vector resource, which returns an array view.

Methods

impl<'a, T> ArrayView<'a, T> where
    T: RefFactory, 

pub fn new(data: &'a [u8]) -> Self

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

The returned array view does not own the data.

pub fn len(&self) -> usize

Number of elements in the array.

pub fn is_empty(&self) -> bool

Return true if the array is empty.

pub fn at(&self, index: usize) -> <T as Struct<'a>>::Item

Returns a read-only handle to the element in the array at position index.

Panics

Panics if index is greater than or equal to ArrayView::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) -> ArrayViewIter<'a, T>

Returns an iterator to the elements of the array.

pub fn as_bytes(&self) -> &[u8]

Returns a raw bytes representation of the underlying array data.

Trait Implementations
