Struct NDArray 

pub struct NDArray {
    pub unique_id: i32,
    pub timestamp: EpicsTimestamp,
    pub time_stamp: f64,
    pub dims: Vec<NDDimension>,
    pub data: NDDataBuffer,
    pub attributes: NDAttributeList,
    pub codec: Option<Codec>,
    pub pool_id: u64,
    pub data_size: usize,
}

N-dimensional array with typed data buffer.

Fields

unique_id: i32

timestamp: EpicsTimestamp

time_stamp: f64

Separate double-precision timestamp (C++ double timeStamp), independent of epicsTS.

dims: Vec<NDDimension>

data: NDDataBuffer

attributes: NDAttributeList

codec: Option<Codec>

pool_id: u64

Identity of the pool that allocated this array (C++ pNDArrayPool). 0 means the array was not allocated through any pool. NDArrayPool::release verifies this matches its own id before returning the buffer to the free list.

data_size: usize

Requested byte count at allocation time (C++ dataSize). This is the exact num_elements * element_size requested, NOT the allocator-rounded Vec capacity. Pool memory accounting adds/subtracts this exact value.

Implementations

impl NDArray

pub fn new(dims: Vec<NDDimension>, data_type: NDDataType) -> Self

Create a new NDArray with zeroed buffer matching dimensions.

pub fn with_data(dims: Vec<NDDimension>, data: NDDataBuffer) -> Self

Create an NDArray wrapping an already-built data buffer.

The array is not pool-allocated (pool_id == 0); data_size is taken from the buffer’s element count. Use this when a producer fills its own buffer instead of allocating through an crate::ndarray_pool::NDArrayPool.

pub fn info(&self) -> NDArrayInfo

Compute layout info for this array (matching C++ NDArray::getInfo).

For 3D arrays, reads the ColorMode attribute to determine which dimension is X, Y, and color (RGB1, RGB2, or RGB3 layout).

pub fn report(&self, details: i32) -> String

Produce a diagnostic text dump (matching C++ NDArray::report).

details > 5 additionally lists attributes.

pub fn validate(&self) -> ADResult<()>

Validate that buffer length matches dimension product.

Trait Implementations

impl Clone for NDArray

fn clone(&self) -> NDArray

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NDArray

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
