pub struct Bootstrap { /* private fields */ }Expand description
Manages the flow of obtaining bootstrap peer addresses from various sources and also writes to the bootstrap cache.
The sources are tried in the following order while reading:
- Environment variable
ANT_PEERS - Command-line provided addresses
- Bootstrap cache file on disk
- Network contacts endpoints
Addresses are returned one at a time via the next_addr method.
It handles asynchronous fetching from the cache and contacts endpoints,
ensuring only one fetch is in progress at a time.
If no more addresses are available from any source, next_addr returns an error.
It is expected that the caller will retry next_addr later to allow
for asynchronous fetches to complete.
Implementations§
Source§impl Bootstrap
impl Bootstrap
pub async fn new(config: BootstrapConfig) -> Result<Self>
Sourcepub fn next_addr(&mut self) -> Result<Option<Multiaddr>>
pub fn next_addr(&mut self) -> Result<Option<Multiaddr>>
Returns the next address from the sources. Returns Ok(None) if we are waiting for a source to return more
addresses.
Error if we have exhausted all sources and have no more addresses to return.
This does not start any dial attempts, it returns the next address to dial.
Use trigger_bootstrapping_process to poll the dialing process.
Sourcepub fn trigger_bootstrapping_process<B: NetworkBehaviour>(
&mut self,
swarm: &mut Swarm<B>,
contacted_peers: usize,
) -> bool
pub fn trigger_bootstrapping_process<B: NetworkBehaviour>( &mut self, swarm: &mut Swarm<B>, contacted_peers: usize, ) -> bool
Manages the bootstrapping process by attempting to dial peers from the available addresses.
Returns true if the bootstrapping process has ended (either due to successful connection or due to exhaustion
of addresses), otherwise false.
pub fn on_connection_established( &mut self, peer_id: &PeerId, endpoint: &ConnectedPoint, )
pub fn on_outgoing_connection_error(&mut self, peer_id: Option<PeerId>)
