Struct DownloadCache 

pub(crate) struct DownloadCache {
    pub(crate) Entries: HashMap<String, String>,
}

Fields

Entries: HashMap<String, String>

The core data structure for the cache. Key: A unique string like “x86_64-pc-windows-msvc/NODE/24”. Value: The full version string, like “v24.0.0”.

Implementations
