[][src]Module rustc_mir::borrow_check::location

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Structs

LocationIndexInternal
LocationTableInternal

Maps between a MIR Location, which identifies a particular statement within a basic block, to a "rich location", which identifies at a finer granularity. In particular, we distinguish the start of a statement and the mid-point. The mid-point is the point just before the statement takes effect; in particular, for an assignment A = B, it is the point where B is about to be written into A. This mid-point is a kind of hack to work around our inability to track the position information at sufficient granularity through outlives relations; however, the rich location table serves another purpose: it compresses locations from multiple words into a single u32.
