Struct ZarrArray 

pub struct ZarrArray { /* private fields */ }

A chunked N-dimensional array stored in a Zarr directory store.

Implementations

impl ZarrArray

pub fn create( store: DirectoryStore, path: &str, shape: Vec<u64>, chunks: Vec<u64>, dtype: DataType, version: ZarrVersion, ) -> Result<Self>

Create a new Zarr array.

pub fn create_with_options( store: DirectoryStore, path: &str, shape: Vec<u64>, chunks: Vec<u64>, dtype: DataType, version: ZarrVersion, fill_value: f64, compress: bool, ) -> Result<Self>

Create a new Zarr array with explicit fill value and compression option.

pub fn open(store: DirectoryStore, path: &str) -> Result<Self>

Open an existing Zarr array from a store.

pub fn shape(&self) -> &[u64]

Array shape.

pub fn chunk_shape(&self) -> &[u64]

Chunk shape.

pub fn data_type(&self) -> DataType

Data type.

pub fn version(&self) -> ZarrVersion

Zarr version.

pub fn ndim(&self) -> usize

Number of dimensions.

pub fn num_chunks(&self) -> Vec<u64>

Number of chunks along each dimension.

pub fn read_chunk(&self, coords: &[u64]) -> Result<Vec<f64>>

Read a single chunk. Returns fill values if the chunk does not exist.

pub fn write_chunk(&self, coords: &[u64], data: &[f64]) -> Result<()>

Write a single chunk.

pub fn get(&self, start: &[u64], end: &[u64]) -> Result<Vec<f64>>

Read a rectangular selection from the array.

start and end are per-dimension half-open ranges [start, end). Returns data in C-order (row-major).

pub fn set(&self, start: &[u64], end: &[u64], data: &[f64]) -> Result<()>

Write a rectangular selection into the array.

start and end define the half-open range per dimension. data is in C-order.

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

Formats the value using the given formatter.
