View Source simdjson (simdjsone v0.3.0)
Fast decoding of JSON using simdjson C++ library.
By default JSON decoder uses the atomnull to represent JSON nulls. To modify this behavior, set the following configuration option to another atom value (e.g. nil for Elixir): {simdjsone, [{null, nil}]}.Link to this section Summary
Types
Decode options:
return_maps- decode JSON object as mapobject_as_tuple- decode JSON object as a proplist wrapped in a tuplededup_keys- eliminate duplicate keys from a JSON objectuse_nil- decode JSON "null" asnil{null_term, V}- use the given valueVfor a JSON "null"
Encode options:
uescape- escape UTF-8 sequences to produce a 7-bit clean outputpretty- return JSON using two-space indentationuse_nil- encode the atomnilasnull`</li> <li>`escape_fwd_slash- escape the/character (useful when encoding URLs){bytes_per_red, N}- whereN>= 0 - This controls the number of bytes that Jiffy will process as an equivalent to a reduction. Each 20 reductions we consume 1% of our allocated time slice for the current process. When the Erlang VM indicates we need to return from the NIF.
