Parameters ---------- path : str, path object, or file-like object String, path object (implementing ``os.PathLike[str]``), or file-like object implementing a binary ``read()`` function. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: ``file://localhost/path/to/table.feather``. columns : sequence, default None If not provided, all columns are read. use_threads : bool, default True Whether to parallelize reading using multiple threads. {storage_options} dtype_backend : {{'numpy_nullable', 'pyarrow'}}, default 'numpy_nullable' Back-end data type applied to the resultant :class:`DataFrame` (still experimental). Behaviour is as follows: * ``"numpy_nullable"``: returns nullable-dtype-backed :class:`DataFrame` (default). * ``"pyarrow"``: returns pyarrow-backed nullable :class:`ArrowDtype` DataFrame. .. versionadded:: 2.0 Returns ------- type of object stored in file Examples -------- >>> df = pd.read_feather("path/to/file.feather") # doctest: +SKIP rrrNrbFr!)r*r,Znumpy_nullable)_arrow_dtype_mapping)Z types_mapper)rrrZ(pandas.core.arrays.arrow.extension_typesr r r no_defaultr read_featherr$r-Z read_tablepandas.io._utilr1Z to_pandasgetpdZ ArrowDtyper NotImplementedError) rr*r,rr.rpandasr%Zpa_tabler1r&r&r'r3Es8+      r3)N) rr rrrrrrrr) rr)r*r+r,r-rrr.r/rr )&__doc__ __future__rtypingrrZpandas._configrZ pandas._libsrZpandas.compat._optionalrZpandas.util._decoratorsrZpandas.util._validatorsr r8r6Zpandas.core.apir Zpandas.core.shared_docsr r4r Zpandas.io.commonr collections.abcrrZpandas._typingrrrrrr(r2r3r&r&r&r's2
