Extension trait for BorrowedMutBuffer that allows obtaining strongly-typed views over points and attributes.

Provided Methods

fn view_mut<'b, T: PointType>(&'b mut self) -> PointViewMut<'a, 'b, Self, T>

where 'a: 'b,

Get a strongly typed view of the point data of this buffer. This view allows mutating the point data!

Panics

If T::point_layout() does not match self.point_layout()

fn view_attribute_mut<'b, T: PrimitiveType>( &'b mut self, attribute: &PointAttributeDefinition, ) -> AttributeViewMut<'a, 'b, Self, T>

where 'a: 'b,

Get a strongly typed view of the attribute of all points in this buffer. This view allows mutating the attribute data!

Panics

If attribute is not part of the PointLayout of this buffer.
If T::data_type() does not match attribute.datatype()

fn transform_attribute<'b, T: PrimitiveType, F: Fn(usize, T) -> T>( &'b mut self, attribute: &PointAttributeDefinition, func: F, )

where 'a: 'b,

Apply a transformation function to the given attribute of all points within this buffer. This function is helpful if you want to modify a single attribute of a buffer in-place and works for buffers of all memory layouts. For columnar buffers, prefer using get_attribute_range_mut to modify attribute data in-place.

This function does not support attribute type conversion, so the type T must match the PointAttributeDataType of attribute!

The conversion function takes the current value of the attribute as a strongly typed T and returns the new value for the attribute. It also takes the index of the point within the buffer, so that func can access additional data.

Panics

If attribute is not part of the PointLayout of this buffer.
If T::data_type() does not equal attribute.datatype()

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
