diots (for "documented io-ts" ) augments
io-ts decoders. It provides a parallel set of decoder factory functions
(such as string, struct, etc), with the main difference
that diots decoders also preserve structural metadata that can be inspected
through the meta property. Additionally, the decoders can be
documented with the documentation tagger doc, which lets you write
documentation using kbts, "kbts").
The diots decoders are compatible with/can substitute for native
io-ts decoders, and the latter can be lifted into the diots realm
using the atomic function.
It provides the docgen module, which inspects decoder's structural
metadata fields and generate kbts documentation.
