Trait Array 

pub trait Array:
    Any
    + Send
    + Sync {
    // Required methods
    fn as_any(&self) -> &dyn Any;
    fn as_any_mut(&mut self) -> &mut dyn Any;
    fn shape(&self) -> Vec<usize>;
    fn dtype(&self) -> DLDataType;
    fn device(&self) -> DLDevice;
    fn as_dlpack(
        &self,
        device: DLDevice,
        stream: Option<i64>,
        max_version: DLPackVersion,
    ) -> Result<DLPackTensor, ParseError>;
    fn copy(&self) -> Box<dyn Array>;
}

Storage hook for one per-atom field of a ConFrameBuilder.

Implementors hold the raw bytes for a single field (e.g. all atom positions as a (N, 3) f64 block) and expose them via DLPack so downstream consumers can map a numpy / Eigen / torch view onto the same memory zero-copy.

Required Methods

fn as_any(&self) -> &dyn Any

&dyn Any access for downcast (mirrors metatensor’s pattern).

fn as_any_mut(&mut self) -> &mut dyn Any

&mut dyn Any access for downcast.

fn shape(&self) -> Vec<usize>

Shape of the underlying tensor.

fn dtype(&self) -> DLDataType

DLPack dtype of the elements.

fn device(&self) -> DLDevice

Device residency of the storage.

fn as_dlpack( &self, device: DLDevice, stream: Option<i64>, max_version: DLPackVersion, ) -> Result<DLPackTensor, ParseError>

Export a DLPack-managed tensor view of this array.

device requests the consumer’s preferred device; CPU implementors return Err(ParseError::ValidationError(...)) when asked for a non-CPU device they cannot service. stream is the consumer’s stream (CUDA / ROCm / SYCL); CPU backings ignore it.

fn copy(&self) -> Box<dyn Array>

Deep-copy this array (used by ConFrameBuilder::clone + move_data-style ops). Default impl just clones through the implementor’s natural mechanism.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<T> Array for Arc<RwLock<ArrayD<T>>>

where T: 'static + Send + Sync + Clone + Default + GetDLPackDataType + DLPackPointerCast,

Default Rust backing for the Array trait: shared, lockable, dynamic-rank ndarray. Matches metatensor v2’s Arc<RwLock<ArrayD<T>>> choice and inherits its DLPack + concurrency semantics.

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

fn shape(&self) -> Vec<usize>

fn dtype(&self) -> DLDataType

fn device(&self) -> DLDevice

fn as_dlpack( &self, device: DLDevice, _stream: Option<i64>, _max_version: DLPackVersion, ) -> Result<DLPackTensor, ParseError>

fn copy(&self) -> Box<dyn Array>
