source§fn point_layout(&self) -> &PointLayout
fn point_layout(&self) -> &PointLayout
Returns the
PointLayout
of this buffer. The PointLayout
describes the structure of a single
point at runtime. Read moresource§unsafe fn get_attribute_unchecked(
&self,
attribute_member: &PointAttributeMember,
index: usize,
data: &mut [u8]
)
unsafe fn get_attribute_unchecked( &self, attribute_member: &PointAttributeMember, index: usize, data: &mut [u8] )
Like
get_attribute
, but performs no check whether the attribute actually is part of this buffers PointLayout
or not. Because of this, this function accepts a PointAttributeMember
instead of a PointAttributeDefinition
,
and this PointAttributeMember
must come from the PointLayout
of this buffer! The benefit over get_attribute
is that this function skips the include checks and thus will be faster if you repeatedly want to get data for a
single attribute Read moresource§fn as_columnar(&self) -> Option<&dyn ColumnarBuffer<'a>>
fn as_columnar(&self) -> Option<&dyn ColumnarBuffer<'a>>
Try to get a reference to
self
as a ColumnarBuffer
. Returns None

does not
implement ColumnarBuffer

point_range: Range<usize>,

)
fn get_attribute_range( &self, attribute: &PointAttributeDefinition, point_range: Range<usize>, data: &mut [u8] )
Writes the data for the given
attribute
of the given range of points into data
. The attribute data will
be tightly packed in data
, irregardless of the memory layout of this buffer. The attribute values might not
be correctly aligned, if the alignment requirement of attribute.datatype()
is larger than the size of the
attribute. All of the built-in attributes in pasture have alignments that are less than or equal to their size,
so for built-in attributes you can assume that the attributes in data
are correctly aligned. Read moresource§fn view<'b, T: PointType>(&'b self) -> PointView<'a, 'b, Self, T>where

Get a raw view over the given
attribute
from this point buffer. Unlike the typed view that view_attribute
returns, this view dereferences to byte slices, but it is potentially more efficient to use than calling
get_attribute
