Implementations

impl AnnounceCache

pub fn new(base_path: PathBuf) -> Self

Create an announce cache at the given directory. The directory must already exist (created by ensure_storage_dirs).

pub fn store( &self, packet_hash: &[u8; 32], raw: &[u8], interface_name: Option<&str>, ) -> Result<()>

Store a cached announce to disk.

packet_hash: 32-byte packet hash (used as filename) raw: raw announce bytes (pre-hop-increment) interface_name: optional interface name string

pub fn get( &self, packet_hash: &[u8; 32], ) -> Result<Option<(Vec<u8>, Option<String>)>>

Retrieve a cached announce from disk.

Returns (raw_bytes, interface_name_or_none).

pub fn clean(&self, active_hashes: &[[u8; 32]]) -> Result<usize>

Remove cached announces whose packet hashes are not in the active set.

active_hashes: set of packet hashes that should be kept. Returns the number of removed entries.
