-- | Exposes functions for building JSON decoders that harness the power
-- of the simdjson::ondemand API.
--
-- A decoder is really a function from a simdjson `Value` to some Haskell type in the `DecoderM` monad.
-- It looks like
-- [Data.Aeson.parseJSON](https://hackage.haskell.org/package/aeson-2.0.2.0/docs/Data-Aeson.html#v:parseJSON),
-- except the `Value` is opaque and can only be used when it's passed by
-- reference across the C FFI.
--
-- `decodeEither` provides the quickest way to feed the initial `Value` to your decoder.
-- It does this by obtaining a top-level `Value` from the simdjson document
-- instance. Decoding a document into a scalar from a `Value` is not supported
-- by simdjson. While simdjson can cast a document directly to a scalar, this
-- library currently exposes no interface for this.
