pamoja 0.1.17

//! The whole pamoja device SDK in one crate.
//!
//! pamoja is one memory-safe Rust core with a crate per capability, so a build
//! carries only the crates it names. This crate is the other way in: every
//! capability sits behind a feature, all on by default, so `cargo add pamoja` is
//! the whole framework, the way `npm install pamoja`, `pip install pamoja`, and
//! `dotnet add package Pamoja` are in the bindings.
//!
//! Each module re-exports the crate of the same name: `pamoja::codec` is
//! `pamoja-codec`, `pamoja::mqtt` is `pamoja-mqtt`, and `pamoja::core` is
//! `pamoja-core`, the traits every capability implements. The types, the
//! documentation, and the examples are those of the crate, so code moves between
//! `use pamoja::codec::CborCodec` and `use pamoja_codec::CborCodec` with no other change.
//!
//! ```toml
//! [dependencies]
//! pamoja = "0.1"
//! ```
//!
//! A build that needs only some capabilities names them, and takes on only
//! their dependencies:
//!
//! ```toml
//! [dependencies]
//! pamoja = { version = "0.1", default-features = false, features = ["std", "codec", "security"] }
//! ```
//!
//! # Example
//!
//! A reading taken off a wire, smoothed, packed for a metered link, and signed so
//! the gateway that receives it can tell which device sent it, with nothing plugged
//! in:
//!
//! ```
//! use pamoja::codec::{decode_deltas, encode_deltas};
//! use pamoja::kit::Smoother;
//! use pamoja::security::{DeviceIdentity, PublicIdentity};
//! use pamoja::sensors::ds18b20::{temperature_from_celsius, Resolution, Scratchpad};
//!
//! // A stand-in for the thermometer. On a running node these nine bytes arrive from
//! // the 1-Wire bus; here the library builds what a part at 25.0625 C would send.
//! let off_the_bus = Scratchpad::new(
//!     temperature_from_celsius(25.0625, Resolution::Bits12),
//!     Resolution::Bits12,
//!     75,
//!     -10,
//! )
//! .to_bytes();
//!
//! // The part checksums every read, so a value mangled on a long run is an error
//! // rather than a plausible temperature a couple of degrees off.
//! let celsius = Scratchpad::parse(&off_the_bus)
//!     .expect("the checksum matches")
//!     .temperature_celsius();
//! assert_eq!(celsius, 25.0625);
//!
//! // Readings jitter, so smooth them and send a batch rather than one at a time.
//! let mut smoother = Smoother::new(0.5);
//! let batch: Vec<i64> = [celsius, celsius + 0.5, celsius + 0.4]
//!     .into_iter()
//!     .map(|sample| (smoother.update(sample) * 100.0).round() as i64)
//!     .collect();
//! let packed = encode_deltas(&batch);
//! assert!(packed.len() < batch.len() * 8);
//!
//! // Sign the batch. The signature travels with the payload as one message, so a
//! // gateway holding only the public key gets the payload back once it checks out.
//! let device = DeviceIdentity::from_seed(&[7u8; 32]);
//! let message = device.sign_message(&packed);
//!
//! let known = PublicIdentity::from_bytes(&device.public().to_bytes())?;
//! let payload = known.verify_message(&message)?;
//! assert_eq!(decode_deltas(payload).expect("a valid batch"), batch);
//! # Ok::<(), pamoja::core::Error>(())
//! ```

//! # Features
//!
//! One feature per capability, named as its crate is without the prefix, and all

//! | `loopback` | `pamoja::loopback` | [pamoja-loopback](https://docs.rs/pamoja-loopback) |
//! | `sync` | `pamoja::sync` | [pamoja-sync](https://docs.rs/pamoja-sync) |
//! | `ladder` | `pamoja::ladder` | [pamoja-ladder](https://docs.rs/pamoja-ladder) |
//! | `bus` | `pamoja::bus` | [pamoja-bus](https://docs.rs/pamoja-bus) |

//! | `dashboard` (off by default) | `pamoja::dashboard` | [pamoja-dashboard](https://docs.rs/pamoja-dashboard) |
//!
//! Six of those capabilities' chapters hold more than one capability, and each has a
//! feature that turns on exactly its own, so a build can name a domain instead of listing
//! its parts. They are checked against the capability map, so a new capability cannot fall
//! out of its group:
//!
//! | Group feature | Turns on |
//! | --- | --- |
//! | `field-io` | `serial`, `modbus`, `can`, `gpio` |
//! | `sensing` | `sensors`, `actuators` |
//! | `radio` | `lora`, `lorawan`, `mesh`, `routing` |
//! | `trust` | `audit`, `session`, `update`, `power`, `telemetry` |
//! | `transports` | `mqtt`, `coap`, `loopback`, `sync`, `ladder`, `bus`, `sim` |
//! | `profiles` | `profile`, `ros2`, `zenoh` |
//!
//! ```toml
//! [dependencies]
//! pamoja = { version = "0.1", default-features = false, features = ["std", "field-io"] }
//! ```
//!
//! `std`, on by default, turns on the standard-library layer of the crates that
//! have one (`pamoja-core`, `pamoja-lora`, `pamoja-mavlink`) and implies `alloc`,
//! which adds the owned channel plans, tables, and message shapes of `pamoja-lora`,
//! `pamoja-mesh`, `pamoja-routing`, and `pamoja-mavlink`. With both off and only
//! `no_std` capabilities named, the crate builds for a bare-metal target; CI
//! compiles it for `thumbv7em-none-eabihf`. The crates keep their finer switches
//! (the LoRa region set, the kit's helper groups, the MAVLink serial driver), so
//! depend on the crate itself when you need one of those. `dashboard` adds the
//! fleet dashboard, a web server, and is off by default.
