In the Rust programming language, a trait is a very important concept that can include: functions, constants, types, etc. To put it simply, a trait defines shared behavior in an abstract way. It can be thought of as an interface in some languages, but there are certain differences, which will be introduced below. 1. Member … Read more
SIMD Implementation for Aho-Corasick on AArch64 The main purpose of this PR is to add a SIMD implementation for Teddy (a key data structure) on AArch64. Previously, Teddy utilized x86-64 SIMD instructions, specifically SSSE3 and AVX2. This PR reorganizes Teddy’s main implementation into a new Vector trait and provides implementations of the Vector trait for … Read more
