Daniel Lemire 41cb909604 Minor change to handle paranoid compilers. (#1732) 2021-10-12 17:23:45 -04:00
strager d036fdf919 Reduce #include bloat (<iostream>) (#1697)
Including <iostream> has two problems:

* Compile times are worse because of over-inclusion
* Binary sizes are worse when statically linking libstdc++ because
  iostreams cannot be dead-code-stripped

simdjson only needs std::ostream. Include the header declaring only what
we need (<ostream>), omitting stuff we don't need (std::cout and its
initialization, for example).

This commit should not change behavior, but it might break users who
assume that including <simdjson/simdjson.h> will make std::cout
available (such as many of simdjson's own files).

Paul Dreik f93fb21c95 optionally disable deprecated apis (#1271)
Introduce cmake option SIMDJSON_DISABLE_DEPRECATED_API (default Off)
which turns off deprecated simdjson api functions by setting the macro
 SIMDJSON_DISABLE_DEPRECATED_API.

For non-cmake users, users will have to set SIMDJSON_DISABLE_DEPRECATED_API
by some other means to disable the api.
