    pub dims: Vec<u64>,
    pub chunk_shape: Vec<u64>,
    pub data: Vec<f64>,
    pub attrs: Vec<(String, String)>,
}

A chunked dataset: stores data split into uniform-sized chunks.

Fields

name: String

Dataset name.

dims: Vec<u64>

Full dataset dimensions.

chunk_shape: Vec<u64>

Chunk shape.

data: Vec<f64>

Data (f64), stored flat across all chunks.

attrs: Vec<(String, String)>

Attributes.

Implementations
