Features that matter to me:
- no allocation, ever
- parsing/generating data incrementally from/into segmented buffers
- full arbitrary-precision decimal support without imposing a decimal
representation on me
- not imposing any string or blob type
- fast conversion between numbers and text, with correct shortest
representation for floating-point
Unfortunately your library does not satisfy all of those criteria, so
it is not very useful to me.
Main problem appears to be that the parser is hardcoded to convert the
values into a specific type.
In practice I use JSON as a self-describing
serialization/deserialization system in text form, which also happens
to work well as a representation to transmit data across systems and
I do not want to convert a stream of JSON bytes into a
boost::json::value type, which might already be a lossy conversion, I
want to convert it directly to my type.
