Struct MaybeInitAttributeBuffer 

pub struct MaybeInitAttributeBuffer { /* private fields */ }

Implementations

impl MaybeInitAttributeBuffer

pub fn new( len: usize, component_type: ComponentDataType, num_components: usize, ) -> Self

Creates a new attribute buffer with the given component type and number of components. This allocates memory for the buffer, but does not initialize it.

pub fn as_slice_unchecked<Data, const N: usize>(&self) -> &[Data]

where Data: Vector<N>, Data::Component: DataValue,

Returns a slice of all the values in the buffer casted to the static type Data. Safety: Callers must know exactly which part of resulting slice is valid.
Dereferencing the uninitialized part of the slice is undefined behavior. Moreover, ‘num_components * component_type.size()’ must equal ‘std::mem::size_of::()’.

pub fn write<Data, const N: usize>(&mut self, idx: usize, data: Data)

where Data: Vector<N>, Data::Component: DataValue,

pub fn write_type_unchecked<Data, const N: usize>( &mut self, idx: usize, data: Data, )

where Data: Vector<N>, Data::Component: DataValue,

Safety: The caller must ensure that the type of the data matches the type of the buffer. Furthermore, the index must be within the bounds of the buffer.

pub fn len(&self) -> usize

Returns the number of values of the attribute.

pub fn get_component_type(&self) -> ComponentDataType

Returns the component type of the attribute.

pub fn get_num_components(&self) -> usize

Returns the number of components.
