Expand description
§续命
§Note
DO NOT USE THIS IN ANY CODE YOU DON’T WANT MESS UP
§Why?
You want to expand some lifetime without either call *::leak()
§How?
An issue had opened for decades
In essence, it’s because static checking of multi-level lifetimes itself is inherently complex
§Credits
Also check examples in cve-rs,
to find ‘what kind of memory vulnerabilities we could face with unconditional lifetime expand’?
