Struct LVArray

#[repr(C)]
pub struct LVArray<const D: usize, T> { /* private fields */ }

Internal LabVIEW array representation.

todo: does this follow cluster packing rules? yes but lots breaks.

Implementations

impl<const D: usize, T> LVArray<D, T>

implement a basic, unsafe API that works for packed usage on 32 bit targets.

It is copy only as we must copy out of the pointers.

pub fn dimension_sizes(&self) -> LVArrayDims<D>

Get the dimensions of the array.

pub fn element_count(&self) -> usize

Get the total number of elements in the array across all dimensions.

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

Get the value directly from the array. This is an unsafe method used on 32 bit targets where the packed structure means we cannot access a slice.

On 64 bit targets use LVArray::data_as_slice instead.

Safety

If the index is out of the range then it is undefined behaviour.

pub unsafe fn set_value_unchecked(&mut self, index: usize, value: T)

Set the value at the index. This is an unsafe method used on 32 bit targets where the packed structure means we cannot access a slice.

On 64 bit targets use LVArray::data_as_slice_mut instead.

Safety

If the index is out of range then it is undefined behaviour.

impl<const D: usize, T> LVArray<D, T>

pub fn data_as_slice(&self) -> &[T]

Get the data component as a slice.

Note: for muti-dimension arrays this is a raw structure so you will need to understand the dimenisons and data ordering.

For 1D arrays this can just be used as the data contents.

pub fn data_as_slice_mut(&mut self) -> &mut [T]

Get the data component as a mutable slice.

Note: for multi-dimension arrays this is a raw structure so you will need to understand the dimensions and data ordering.

For 1D arrays this can just be used as the data contents.
