`iterable-io` is a small Python library that provides an adapter so
that it's possible to read from
[iterable](https://docs.python.org/3/glossary.html#term-iterable)
objects in the same way as
[file-like](https://docs.python.org/3/glossary.html#term-file-object)
objects.

It is primarily useful as "glue" between two incompatible
interfaces. As an example, in the case where one interface expects a
file-like object to call `.read()` on, and the other only provides a
generator of bytes.

One way to solve this issue would be to write all the bytes in the
generator to a temporary file, then provide that file instead, but if
the generator produces a large amount of data then this is both slow
to start, and resource-intensive.

This library allows streaming data between these two incompatible
interfaces so as data is requested by `.read()`, it's pulled from the
iterable. This keeps resource usage low and removes the startup
