Struct ArrayBuf 

pub struct ArrayBuf<Tag> { /* private fields */ }

Generic dense N-dimensional buffer parameterized by an element-type tag.

NumericArray = ArrayBuf<NumericArrayEnum> and PackedArray = ArrayBuf<PackedArrayEnum>. Each provides specialized constructors (from_slice<T: …Element>) and a typed slice view; shape, byte access, and element count are shared via this struct.

Implementations

impl<Tag: Copy + PartialEq> ArrayBuf<Tag>

pub fn new(data_type: Tag, dimensions: Vec<usize>, bytes: ByteArray) -> Self

Construct from raw parts. Caller is responsible for ensuring bytes.len() == prod(dimensions) * element_size.

pub fn data_type(&self) -> Tag

The concrete element-type tag.

pub fn dimensions(&self) -> &[usize]

Multi-dimensional shape.

pub fn as_bytes(&self) -> &[u8]

Raw byte buffer.

pub fn rank(&self) -> usize

Number of dimensions.

pub fn element_count(&self) -> usize

Total element count = product of dimensions.

pub fn byte_count(&self) -> usize

Total byte length of the buffer.

pub fn from_slice<T: ArrayElement<Tag>>( dimensions: Vec<usize>, slice: &[T], ) -> Self

Construct from a typed slice. Dimensions must satisfy prod(dimensions) == slice.len().

pub fn try_as_slice<T: ArrayElement<Tag>>(&self) -> Option<&[T]>

Try to view the buffer as a slice of T. Returns None if T’s tag doesn’t match this array’s data_type.

Trait Implementations

impl<Tag: Into<NumericArrayEnum> + Copy + PartialEq> NumericArrayRead for ArrayBuf<Tag>

fn data_type(&self) -> NumericArrayEnum

The element-type tag.

fn dimensions(&self) -> &[usize]

The multi-dimensional shape (row-major).

fn as_bytes(&self) -> &[u8]

The flat little-endian byte buffer.

fn rank(&self) -> usize

Number of dimensions.

fn element_count(&self) -> usize

Total element count = product of dimensions.

fn byte_count(&self) -> usize

Total byte length of the buffer.

fn element_size(&self) -> usize

Bytes per element.

fn try_as_slice<T: ArrayElement<NumericArrayEnum>>(&self) -> Option<&[T]>

View the buffer as &[T] if T’s element type matches; else None.

impl<Tag: Ord> Ord for ArrayBuf<Tag>

fn cmp(&self, other: &ArrayBuf<Tag>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<Tag: PartialEq> PartialEq for ArrayBuf<Tag>

fn eq(&self, other: &ArrayBuf<Tag>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
