RcppSimdJson 0.1.10 on CRAN: New Upstream

We are happy to share that the RcppSimdJson package has been updated to release 0.1.10.

RcppSimdJson wraps the fantastic and genuinely impressive simdjson library by Daniel Lemire and collaborators. Via very clever algorithmic engineering to obtain largely branch-free code, coupled with modern C++ and newer compiler instructions, it results in parsing gigabytes of JSON parsed per second which is quite mindboggling. The best-case performance is ‘faster than CPU speed’ as use of parallel SIMD instructions and careful branch avoidance can lead to less than one cpu cycle per byte parsed; see the video of the talk by Daniel Lemire at QCon.

This release updates the underlying simdjson library to version 3.1.8 (also made today). Otherwise we only made a minor edit to the README and adjusted one tweek for code coverage.

The (very short) NEWS entry for this release follows.
