Struct kismet_cache::Key

pub struct Key<'a> {
    pub name: &'a str,
    pub hash: u64,
    pub secondary_hash: u64,
}

Cache keys consist of a filename and two hash values. The two hashes should ideally be computed by distinct functions of the key’s name, but Kismet will function correctly if the hash and secondary_hash are the same. Each hash function must be identical for all processes that access the same sharded cache directory.

The name should not be empty nor start with a dot, forward slash, a backslash: caches will reject any operation on such names with an ErrorKind::InvalidInput error.

Fields

name: &'a str

hash: u64

secondary_hash: u64
