Enum CacheError

pub enum CacheError {
    InvalidCacheEntry,
    OutdatedCacheVersion,
    UnknownCacheVersion,
    UnknownIndexVersion,
    OutdatedRevision,
    InvalidCrateVersion,
}

Errors related to a local index cache

Variants

InvalidCacheEntry

The cache entry is malformed

OutdatedCacheVersion

The cache version is old

UnknownCacheVersion

The cache version is newer than the version supported by this crate

UnknownIndexVersion

The index version is newer than the version supported by this crate

OutdatedRevision

The revision in the cache entry did match the requested revision

This can occur when a git index is fetched and a newer revision is pulled from the remote index, invalidating all local cache entries
