Crate net_sdk 

Net SDK

Ergonomic Rust SDK for the Net mesh network.

The core net crate is the engine. This SDK is what developers actually import.

Example

use net_sdk::{Net, Backpressure};
use futures::StreamExt;

let node = Net::builder()
    .shards(4)
    .backpressure(Backpressure::DropOldest)
    .memory()
    .build()
    .await?;

// Emit events
node.emit(&serde_json::json!({"token": "hello"}))?;
node.emit_raw(b"{\"token\": \"world\"}" as &[u8])?;

// Subscribe to a stream
let mut stream = node.subscribe(Default::default());
while let Some(event) = stream.next().await {
    let event = event?;
    println!("{}", event.raw_str().unwrap_or("<non-utf8>"));
}

node.shutdown().await?;

Modules

capabilities

Capability declarations — what a node can do.

compute

Compute surface — MeshDaemon + DaemonRuntime.

config

Simplified configuration builder for the SDK.

cortex

CortEX + RedEX + NetDb surface.

dataforts

Dataforts SDK surface — operator-facing re-exports for the mesh-native blob storage adapter.

error

Unified SDK error type.

groups

HA / scaling overlays on top of DaemonRuntime.

identity

Identity handle — keypair + token cache.

mesh

Multi-peer mesh handle for the SDK.

mesh_rpc

nRPC SDK surface — typed serve_rpc_typed / call_typed over the underlying MeshNode::serve_rpc / call raw-bytes API.

mesh_rpc_resilience

Caller-side resilience helpers for nRPC calls.

meshdb

MeshDB SDK surface — federated query plane above the substrate’s chains.

meshos

MeshOS SDK — daemon-author surface.

stream

Async stream-based event consumption.

subnets

Subnet assignment — hierarchical 4-level grouping for routing and visibility.

Structs

BatchConfig

Batch aggregation configuration.

CapabilityFilter

Filter for querying capabilities

CapabilitySet

Complete capability set for a node.

CausalEvent

A causal event: link + payload.

CausalLink

Causal link — 32 bytes prepended to each event in causal-framed EventFrames.

ChannelConfig

Channel configuration with capability-based access control.

ChannelId

A channel identifier: name + cached canonical hash.

ChannelName

A validated channel name.

DaemonHostConfig

Configuration for a daemon host.

DaemonStats

Runtime statistics for a daemon.

Event

An opaque event - any valid JSON value.

MeshStream

A typed handle to a logical stream within a peer session.

Net

A node on the Net mesh.

NetAdapterConfig

Configuration for the Net adapter.

PermissionToken

A signed, delegatable permission token.

PollRequest

Options for a one-shot poll request.

PollResponse

Response from a poll request.

PublishConfig

Builder-style configuration for a ChannelPublisher.

PublishReport

Outcome of one publish / publish_many call.

RawEvent

A pre-serialized event with cached hash.

Receipt

Receipt from a successful ingestion.

ScalingPolicy

Policy configuration for dynamic shard scaling.

StateSnapshot

A serializable state snapshot at a point in the causal chain.

Stats

Ingestion statistics.

StoredEvent

An event retrieved from storage with its backend-specific ID.

StreamConfig

Per-stream configuration supplied at open_stream time.

StreamStats

Per-stream statistics snapshot. Cheap to produce (reads a handful of atomics) and safe to poll at arbitrary frequency.

SubnetId

Hierarchical subnet identifier.

SubnetPolicy

Policy for assigning nodes to subnets based on capability tags.

TokenScope

Actions a token can authorize.

Enums

AckReason

Why a Subscribe or Unsubscribe was rejected.

CloseBehavior

What to do with pending outbound packets when a stream is closed.

Filter

A filter predicate for matching events.

MigrationError

Errors from migration operations.

MigrationPhase

Phases of daemon migration.

OnFailure

What to do when one of the per-peer fan-out sends fails.

Ordering

Ordering mode for consumed events.

Reliability

Reliability mode chosen per stream.

TokenError

Errors from token operations.

Visibility

Channel visibility scope.

Constants

VERSION

Crate version, sourced from Cargo.toml at build time. Re- exported so downstream binaries (the net CLI in particular) can report the embedded SDK version without hardcoding a literal that silently drifts on every workspace bump.

Traits

MeshDaemon

A daemon that runs on the mesh.
