Struct pasture_core::containers::AttributeView

pub struct AttributeView<'a, 'b, B: BorrowedBuffer<'a>, T: PrimitiveType>
where
    'a: 'b,
{ /* private fields */ }

A strongly typed view over attribute data of a point buffer. This allows accessing the data for a specific attribute of a PointType using the strong type T instead of as raw memory (i.e. &[u8]). This type makes no assumptions about the memory layout of the underlying buffer, so it only provides access to the attribute data by value. Just as with the PointView type, you cannot create instances of AttributeView directly. Instead, use the BorrowedBuffer::view_attribute function and its variations, which perform the necessary type checking.

Implementations

impl<'a, 'b, B: BorrowedBuffer<'a>, T: PrimitiveType> AttributeView<'a, 'b, B, T>

pub fn at(&self, index: usize) -> T

Get the attribute value at index

Panics

If index is out of bounds

impl<'a, 'b, B: ColumnarBuffer<'a>, T: PrimitiveType> AttributeView<'a, 'b, B, T>

where 'a: 'b,

pub fn at_ref<'c>(&'c self, index: usize) -> &'c T

where 'b: 'c,

Get the attribute value at index as an immutable borrow

Panics

If index is out of bounds

pub fn iter<'c>(&'c self) -> AttributeIteratorByRef<'c, T>

where 'b: 'c,

Returns an iterator over attribute values by immutable reference

Trait Implementations

impl<'a, 'b, B: Clone + BorrowedBuffer<'a>, T: Clone + PrimitiveType> Clone for AttributeView<'a, 'b, B, T>

where 'a: 'b,

fn clone(&self) -> AttributeView<'a, 'b, B, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, 'b, B: Debug + BorrowedBuffer<'a>, T: Debug + PrimitiveType> Debug for AttributeView<'a, 'b, B, T>

where 'a: 'b,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, 'b, B: BorrowedBuffer<'a> + 'a, T: PrimitiveType> IntoIterator for AttributeView<'a, 'b, B, T>

type Item = T

The type of the elements being iterated over.

type IntoIter = AttributeIteratorByValue<'a, 'b, T, B>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a, 'b, 'c, 'd, B1: BorrowedBuffer<'a> + 'a, B2: BorrowedBuffer<'c> + 'c, T: PrimitiveType + PartialEq> PartialEq<AttributeView<'c, 'd, B2, T>> for AttributeView<'a, 'b, B1, T>

fn eq(&self, other: &AttributeView<'c, 'd, B2, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
