[][src]Module rustc_data_structures::svh

⚙️ 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.

Calculation and management of a Strict Version Hash for crates

The SVH is used for incremental compilation to track when HIR nodes have changed between compilations, and also to detect mismatches where we have two versions of the same crate that were compiled from distinct sources.
