bin_io is a crate inspired greatly by nom and
other parser combinator libraries.
But bin_io differs from those crates since
it aims at providing both reading and writing
facilities at the same time, with fewer code.
Add bin_io = "0.2" to your Cargo.toml
In 0.2 bin_io had a massive change, it now uses
references while writing, and no longer needs an owned
copy. This meant that some things needed to change
from the last version, but everything should still
work fine (with minor code changes, seq! in particular),
so check out the documentation!
