# Struct cargo::sources::registry::index::SummariesCache

source ·

    struct SummariesCache<'a> {
        versions: Vec<(Version, &'a [u8])>,
        index_version: &'a str,
    }

Expand description

A representation of the cache on disk that Cargo maintains of summaries. Cargo will initially parse all summaries in the registry and will then serialize that into this form and place it in a new location on disk, ensuring that access in the future is much speedier.

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
