Go developers who work with large datasets, caches, or performance-sensitive code. Familiarity with Go's GC model is helpful but not required.

Тезисы

Comparing two identical 1MB strings takes 1.3 milliseconds. Comparing two 'unique.Handle[string]' values takes 0.31 nanoseconds. That's 4.1 million times faster.

The 'unique' package: a standard library solution for value canonicalization (also called interning). This talk explores the problem it solves, how it works internally with GC-integrated weak pointers, and when you should (and shouldn't) reach for it.
