Struct Metagraph 

Source 
pub struct Metagraph {
    pub netuid: u16,
    pub neurons: Vec<NeuronInfo>,
    pub n: u16,
    pub block: u64,
    /* private fields */

Expand description

In-memory snapshot of a Bittensor subnet’s metagraph.

Call sync to fetch the latest state from a subtensor node.

Fields§

§netuid: u16

Subnet network UID.

§neurons: Vec<NeuronInfo>

All neurons in the subnet at the last sync point.

§n: u16

Number of neurons in the subnet (SubnetworkN).

§block: u64

Block number at which the metagraph was last synced.

Implementations§

Source§

impl Metagraph

Source

pub fn new(netuid: u16) -> Self

Creates an empty metagraph for the given subnet. Call sync to populate.

Source

pub async fn sync( &mut self, client: &OnlineClient<PolkadotConfig>, ) -> Result<()>

Fetches the latest metagraph from a subtensor node, replacing all neuron data. Tries the runtime API first, falling back to individual storage queries.

Source

pub fn quic_miners(&self) -> Vec<QuicAxonInfo>

Returns axon info for active, non-validator neurons advertising QUIC (protocol 4) on a globally routable IPv4 address.

Source

pub fn get_neuron(&self, uid: u16) -> Option<&NeuronInfo>

Looks up a neuron by UID.

Source

pub fn get_uid_by_hotkey(&self, hotkey: &str) -> Option<u16>

Looks up a neuron’s UID by SS58 hotkey.
