Struct CacheEntry 

#[non_exhaustive]
pub struct CacheEntry {
    pub key: String,
    pub path: PathBuf,
    pub metadata: KernelMetadata,
}

A cached kernel entry returned by crate::cache::CacheDir::lookup and crate::cache::CacheDir::store.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: String

Cache key (directory name).

path: PathBuf

Path to the cache entry directory.

metadata: KernelMetadata

Deserialized metadata. Always present on a CacheEntry.

Implementations

pub fn disk_template_path(&self) -> PathBuf

Absolute path to the cached btrfs disk template (<entry>/disk-template.img).

pub fn kconfig_status(&self, current_hash: &str) -> KconfigStatus

Compare this entry’s kconfig hash against current_hash.

pub fn has_extra_kconfig(&self) -> bool
