Re2 hyperscan
WebHyperscan and re2 are 24x to 40x faster than the default Go regexp library and use 7x less memory; Hyperscan and re2’s performance with this specific set of patterns and test data … WebThe Hyperscan compiler API accepts regular expressions and converts them into a compiled pattern database that can then be used to scan data. The API provides three functions that compile regular expressions into databases: hs_compile (): compiles a single expression into a pattern database.

WebHyperscan is an opensource library for regular expression matching developed by Intel. The library includes 4 implementations that use different sets of processor instructions (SSE3, … Webr² Diagnostics, a sister company of Enzyme Research Laboratories (ERL), was incorporated in 1993 as an FDA 21CFR820 registered and an ISO 13485 certified manufacturer and …
WebHighlights. Hyperscan makes use of many different techniques to try to make the regular expression matching task tractable for large numbers of regular expressions. Parts of the regular expression task are unsolved in Hyperscan due to a lack of demand thus far in our target markets — but are not necessarily unsolvable in the Hyperscan framework. WebHyperscan has different match semantics than RE2. Hyperscan reports matches as soon as they are detected. RE2 tries to mimic backtrackers that have greediness and what not. So …
