Lockfile versions

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

V1

Original Cargo.lock format which places checksums in the [[metadata]] table.

V2

Revised Cargo.lock format which is optimized to prevent merge conflicts.

For more information, see: https://github.com/rust-lang/cargo/pull/7070

V3

Encodes Git dependencies with branch = 'master' in the manifest as ?branch=master in their URLs.
