pub struct Cache { /* private fields */ }

A file-backed implementation of Store.

Implementations

impl Cache

pub fn open<P>(path: P) -> Result<Cache, Error>where
    P: AsRef<Path>,

Open an existing cache.

pub fn create<P>(path: P) -> Result<Cache, Error>where
    P: AsRef<Path>,

Create a new cache.

pub fn from(file: File) -> Result<Cache, Error>

Create a new cache from a file.

Trait Implementations

impl Debug for Cache

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Store for Cache

fn get_mut(&mut self, ip: &IpAddr) -> Option<&mut KnownAddress>

Get a known peer address mutably.

fn get(&self, ip: &IpAddr) -> Option<&KnownAddress>

Get a known peer address.

fn remove(&mut self, ip: &IpAddr) -> Option<KnownAddress>

Remove an address from the store.

fn insert(&mut self, ip: IpAddr, ka: KnownAddress) -> bool

Insert a new address into the store. Returns true if the address was inserted, or false if it was already known.

fn iter(
    &'a self
) -> Box<dyn Iterator<Item = (&'a IpAddr, &'a KnownAddress)> + 'a, Global>

Return an iterator over the known addresses.

fn clear(&mut self)

Clears the store of all addresses.

fn len(&self) -> usize

Returns the number of addresses.

fn flush(&mut self) -> Result<(), Error>

Flush data to permanent storage.

fn is_empty(&self) -> bool

Returns true if there are no addresses.

fn seed<S>(
    &mut self,
    seeds: impl Iterator<Item = S>,
    source: Source
) -> Result<(), Error>where
    S: ToSocketAddrs,

Seed the peer store with addresses. Fails if none of the seeds could be resolved to addresses.
