Module data_type 

Zarr data types.

See https://zarr-specs.readthedocs.io/en/latest/v3/core/index.html#data-types.

This submodule re-exports much of the zarrs_data_type crate.

Use the factory functions (e.g. int8, float32, etc.) to create instances of built-in data types.

Custom data types can be implemented by registering structs that implement the traits of zarrs_data_type. A custom data type guide can be found in The zarrs book.
