## Overview

This is a low level package to read feather files. It is not meant to be used by end users, but rather as a building block for other packages that expose user friendly APIs for file IO.

End users are encouraged to use either [FeatherFiles.jl](https://github.com/queryverse/FeatherFiles.jl) or [Feather.jl](https://github.com/JuliaData/Feather.jl) to interact with feather files.

## Getting Started

The package exports two functions: ``featherread`` and ``featherwrite``.

Use the ``featherread`` function to read a feather file:

````julia

data = featherread("testfile.feather")

````

``data`` will then be of type ``ResultSet``. The field ``columns`` is a vector of vectors and holds the actual data columns. The field ``names`` returns the names of the columns. The ``description`` and ``metadata`` fields return additional data from the feather file.

Use the ``featherwrite`` function to write a feather file:

````julia

featherwrite("testfile.feather", column_data, column_names)

````

``columns`` should be a vector of vectors that holds the data to be written. ``column_names`` should be a vector of ``Symbol``s with the column names.

[Douglas Bates](https://github.com/dmbates), [ExpandingMan](https://github.com/ExpandingMan) and [Jacob Quinn](https://github.com/quinnj) deserve most of the credit for the code in this package: their code in the [Feather.jl](https://github.com/JuliaData/Feather.jl) package was the starting point for this package here. They are of course not responsible for any errors introduced by myself in this package here.
