Dirkjan Ochtman 2d942bbfc9 Box up the BitVec array 
The `Search::best` field will take about 8000 bytes. In some of our usage
with rayon, this appeared to cause stack overflows. Boxing it up makes the
code slower by about 1-2%, but should hopefully avoid stack overflows.

instant-segment: fast English word segmentation in Rust

Documentation Crates.io Build status License: Apache 2.0

instant-segment is a fast Apache-2.0 library for English word segmentation. It is based on the Python wordsegment project written by Grant Jenkins, which is in turn based on code from Peter Norvig's chapter Natural Language Corpus Data from the book Beautiful Data (Segaran and Hammerbacher, 2009).

The data files in this repository are derived from the Google Web Trillion Word Corpus, as described by Thorsten Brants and Alex Franz, and distributed by the Linguistic Data Consortium. Note that this data "may only be used for linguistic education and research", so for any other usage you should acquire a different data set.

For the microbenchmark included in this repository, instant-segment is ~17x faster than the Python implementation. Further optimizations are planned -- see the issues. The API has been carefully constructed so that multiple segmentations can share the underlying state to allow parallel usage.
