Go — Discover Capabilities#

Filter nodes by capability#

nodes, err := node.FindNodes(net.CapabilityFilter{
    RequireTags: []string{"gpu"},
})
if err != nil {
    log.Fatal(err)
}
// nodes is []uint64 — the node ids that match, right now.

FindNodes returns ([]uint64, error) — the matching node ids. Announcements propagate multi-hop (bounded by a hop count), so a match can be a node several hops away. Discovery is advisory — it tells you who can, with no exclusivity.

List tools#

Over a MeshRpc, list the tools folded from the mesh:

rpc, err := net.NewMeshRpc(node)
if err != nil {
    log.Fatal(err)
}
tools, err := rpc.ListTools()
if err != nil {
    log.Fatal(err)
}
for _, t := range tools {
    fmt.Printf("%s v%s tags=%v\n", t.ToolID, t.Version, t.Tags)
}

Folding is asynchronous — poll ListTools until the tool you expect appears rather than assuming it's there on the first call.
