this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Borrows stores the data used in the analyses that track the flow of borrows.

It uniquely identifies every borrow (Rvalue::Ref) by a BorrowIndex, and maps each such index to a BorrowData describing the borrow. These indexes are used for representing the borrows in compact bitvectors.

Add all borrows to the kill set, if those borrows are out of scope at location. That means either they went out of either a nonlexical scope, if we care about those at the moment, or the location represents a lexical EndRegion

A name describing the dataflow analysis that this BitDenotation is supporting. The name should be something suitable for plugging in as part of a filename e.g. avoid space-characters or other things that tend to look bad on a file system, like slashes or periods. It is also better for the name to be reasonably short, again because it will be plugged into a filename. Read more
