aster
Native Rust API for Aster — peer-to-peer transport built on iroh: content-addressed blob storage, CRDT documents, and gossip pub-sub over QUIC.
This is the supported entry point for Rust consumers. It is an idiomatic facade
over the internal aster_transport_core backend (the Python / TypeScript /
Java / Kotlin bindings wrap the same core).
Quick start
use aster::{AsterConfig, Node, RelayMode};
let node = Node::start(
AsterConfig::builder()
.persistent("/var/lib/my-app")
.relay(RelayMode::Default)
.build(),
)
.await?;
// Blobs
let hash = node.blobs().add_bytes(b"hello".to_vec()).await?;
let bytes = node.blobs().read_to_bytes(&hash).await?;
// Docs (deterministic config namespace)
let secret = aster::NamespaceSecret::from_bytes(my_32_byte_seed);
let doc = node.docs().open_or_import_write_namespace(secret).await?;
let author = node.docs().default_author().await?;
doc.set_bytes(&author, b"key".to_vec(), b"val".to_vec()).await?;
node.shutdown().await;
See examples/quickstart.rs for an end-to-end persistence round-trip.
Cargo features
| Feature | Default | Gates |
|---|---|---|
blobs |
✅ | Node::blobs() |
docs |
✅ | Node::docs() |
gossip |
✅ | Node::gossip() |
discovery |
— | mDNS local discovery config |
hooks |
— | (reserved) |
metrics |
— | Node::metrics_prometheus() |
Admission (Node::take_admission()) additionally requires the node to be
started with AsterConfig::builder().hooks(true).
Depending on this crate
Released crates come from Aster's public Forgejo Cargo registry. Configure it once per project:
# .cargo/config.toml
[registries.aster]
index = "sparse+https://forge.emrul.dev/api/packages/Aster/cargo/"
# Cargo.toml
[dependencies]
aster = { version = "0.3", registry = "aster" }
Use the selected release version rather than copying Aster's private fork
graph. Advanced Rust consumers can access the exact Iroh/Fory/Salvo stack via
aster::native. See docs/rust-sdk-consumer-guide.md in the repository for
the registry rollout state, direct-dependency exceptions for proc macros, and
the maintainer-only private-Git fallback.
Status
Step 1 (node + blobs/docs/gossip + admission + deterministic namespaces) is
implemented. Rust-native RPC services are designed but not yet shipped — see
docs/_internal/aster-rust.md.
