Crate ndarray_npy

This crate provides methods to read/write ndarray's ArrayBase type from/to .npy and .npz files.

See the ReadNpyExt and WriteNpyExt extension traits or the read_npy and write_npy convenience functions for reading/writing .npy files.

See NpzReader and NpzWriter for reading/writing .npz files.

See the repository for information about the default features and how to use this crate with Cargo.

Limitations

• Parsing of .npy files is currently limited to files where the descr field of the header dictionary is a Python string literal of the form 'string', "string", '''string''', or """string""".

• WritableElement and ReadableElement are currently implemented only for fixed-size integers, floating point numbers, and bool.

The plan is to add support for more element types (including custom user-defined structs) in the future.

Structs

NpzReader	Reader for .npz files.
NpzWriter	Writer for .npz files.

Enums

WriteNpyExt	Extension trait for writing ArrayBase to .npy files.

Functions

read_npy	Read an .npy file located at the specified path.
write_npy	Writes an array to an .npy file at the specified path.
