1//! # ma-core
2//!
3//! A lean `DIDComm` service library for the ma ecosystem.
4//!
5//! `ma-core` provides the building blocks for ma-capable endpoints:
6//!
7//! - **DID documents** — create, validate, resolve, and publish `did:ma:` documents
8//!   to IPFS/IPNS (via Kubo on native targets). Use [`MaExtension`] to build the
9//!   `ma:` extension field, and [`config::SecretBundle::build_document`] (`config`
10//!   feature) as the single entry point for a complete, signed document.
11//! - **Service inboxes** — bounded, TTL-aware FIFO queues ([`Inbox`])
12//!   for receiving validated messages on named protocol services.
13//! - **Outbound sending** — fire-and-forget delivery of validated [`Message`] objects
14//!   to remote endpoints, serialized to CBOR on the wire.
15//! - **Endpoint abstraction** — the [`MaEndpoint`] trait with pluggable
16//!   transport backends.
17//! - **Transport parsing** — extract endpoint IDs and protocols from DID document
18//!   service strings (`/iroh/<id>/<protocol>`).
19//! - **Identity bootstrap** — secure secret key generation and persistence.
20//!
21//! ## Services
22//!
23//! Every endpoint should provide `/ma/inbox/0.0.1` (the default inbox) when it
24//! wants to receive direct messages. Endpoints may optionally provide
25//! `/ma/ipfs/0.0.1` to publish DID documents
26//! on behalf of others.
27//!
28//! ## Feature flags
29//!
30//! - **`kubo`** — enables native IPFS RPC backend for publishing (native only).
31//! - **`iroh`** — enables the internal iroh QUIC transport backend.
32//! - **`acl`** — enables [`AclMap`], [`check_cap`], capability constants, and
33//!   ACL validation helpers.
34//! - **`config`** — enables [`Config`], [`SecretBundle`], and [`MaArgs`] for
35//!   YAML-based daemon configuration, encrypted secret bundles, and CLI
36//!   argument parsing. Also provides [`config::SecretBundle::build_document`] and
37//!   [`config::SecretBundle::signing_key`] for constructing ready-to-publish DID documents.
38//!
39//! ## Platform support
40//!
41//! Core types (`Inbox`, `Service`, transport parsing, validation)
42//! compile on all targets including `wasm32-unknown-unknown`.
43//!
44//! ### wasm vs native
45//!
46//! - `ma-core` supports both wasm and native targets.
47//! - `IpfsGatewayResolver` (HTTP gateway DID fetch) is available on wasm and native.
48//! - Native IPFS RPC write/pin APIs are native-only (`not(wasm32)` + `kubo` feature).
49//! - wasm builds expose only `ipfs::gateway_resolver` (no native RPC helpers).
50//! - `config` serialization and `SecretBundle` crypto work on wasm.
51//! - `config` filesystem paths, CLI/env merging, and file I/O are native-only.
52//! - If your wasm application needs native IPFS RPC write/pin operations, provide
53//!   them in a native companion layer.
