pub struct CacheMetadataManager<'a, F: FileSystem> { /* private fields */ }

Manages cache metadata for optimized version checking

Implementations

impl<'a, F: FileSystem> CacheMetadataManager<'a, F>

pub const fn new(fs: &'a F) -> Self

pub fn load_metadata<P: AsRef<Path>>( &self, cache_dir: P, ) -> Result<GlobalCacheMetadata, Error>

Load global cache metadata, creating default if it doesn’t exist

Errors

Returns an error if the metadata file exists but cannot be read or parsed

pub fn save_metadata<P: AsRef<Path>>( &self, cache_dir: P, metadata: &GlobalCacheMetadata, ) -> Result<(), Error>

Errors

Returns an error if the metadata cannot be serialized or written to disk

pub fn check_spec_version<P: AsRef<Path>>( &self, cache_dir: P, spec_name: &str, ) -> Result<bool, Error>

Check if a spec’s cache is compatible with current version

Errors

Returns an error if the metadata file cannot be loaded

pub fn update_spec_metadata<P: AsRef<Path>>( &self, cache_dir: P, spec_name: &str, file_size: u64, ) -> Result<(), Error>
