Trait ArrayElement 

pub trait ArrayElement:

    + 'static {
    const DTYPE: DType;

    // Required methods
    fn encode_chunk(values: &[Self]) -> Vec<u8> ;
    fn decode_chunk(bytes: &[u8]) -> Vec<Self>;
    fn fill_element(fill: Option<&FillValue>) -> Self;
}

Unified element type for all array operations.

Implemented by all fixed-width numeric primitives and variable-length types (String, Vec<u8>). The trait provides chunk-level encode/decode and fill-value generation so that a single generic code path handles both.

Required Associated Constants

const DTYPE: DType

The DType this Rust type maps to on disk.

Required Methods

fn encode_chunk(values: &[Self]) -> Vec<u8>

Encodes a chunk’s worth of values into the on-disk byte representation.

fn decode_chunk(bytes: &[u8]) -> Vec<Self>

Decodes bytes produced by encode_chunk back into values.

fn fill_element(fill: Option<&FillValue>) -> Self

Returns the element used for unwritten positions, derived from the array’s fill value (or this type’s natural default when fill is None or not applicable).

Dyn Compatibility

This trait is not dyn compatible.

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