Implementations§

source§

impl MetaAddrChange

source

pub fn addr_strategy(addr: PeerSocketAddr) -> BoxedStrategy<Self>

Returns a strategy which generates changes for addr.

addr is typically generated by the canonical_peer_addr strategy.

source

pub fn addr_changes_strategy( max_addr_change: usize ) -> BoxedStrategy<(MetaAddr, Vec<MetaAddrChange>)>

Returns a strategy which generates a MetaAddr, and a vector of up to max_addr_change changes.

The address and the changes all have matching PeerSocketAddrs.

source

pub fn ready_outbound_strategy_ip() -> BoxedStrategy<IpAddr>

Create a strategy that generates IpAddrs for MetaAddrChanges which are ready for outbound connections.

source

pub fn ready_outbound_strategy_port() -> BoxedStrategy<u16>

Create a strategy that generates port numbers for MetaAddrs which are ready for outbound connections.

Currently, all generated MetaAddrs are the NeverAttemptedGossiped variant.

TODO: Generate all MetaAddr variants, and give them ready fields.

source§

impl MetaAddrChange

source

pub fn addr(&self) -> PeerSocketAddr

Return the address for this change.

source

pub fn set_addr(&mut self, new_addr: PeerSocketAddr)

Set the address for this change to new_addr.

This method should only be used in tests.

source

pub fn untrusted_services(&self) -> Option<PeerServices>

Return the untrusted services for this change, if available.

source

pub fn untrusted_last_seen(&self, now: DateTime32) -> Option<DateTime32>

Return the untrusted last seen time for this change, if available.

source

pub fn last_attempt(&self, now: Instant) -> Option<Instant>

Return the last attempt for this change, if available.

source

pub fn last_response(&self, now: DateTime32) -> Option<DateTime32>

Return the last response for this change, if available.

source

pub fn last_failure(&self, now: Instant) -> Option<Instant>

Return the last failure for this change, if available.

source

pub fn peer_addr_state(&self) -> PeerAddrState

Return the peer connection state for this change.

source

pub fn into_new_meta_addr( self, instant_now: Instant, local_now: DateTime32 ) -> MetaAddr

Returns the corresponding MetaAddr for this change.

source

pub fn local_listener_into_new_meta_addr( self, local_now: DateTime32 ) -> MetaAddr

Returns the corresponding MetaAddr for a local listener change.

This method exists so we don’t have to provide an unused Instant to get a local listener MetaAddr.

§Panics

If this change is not a MetaAddrChange::NewLocal.

source

pub fn apply_to_meta_addr( &self, previous: impl Into<Option<MetaAddr>>, instant_now: Instant, chrono_now: DateTime<Utc> ) -> Option<MetaAddr>

Apply this change to a previous MetaAddr from the address book, producing a new or updated MetaAddr.

If the change isn’t valid for the previous address, returns None.
