aranet_types/
lib.rs

1//! Platform-agnostic types for Aranet environmental sensors.
2//!
3//! This crate provides shared types that can be used by both native
4//! (aranet-core) and WebAssembly (aranet-wasm) implementations.
5//!
6//! # Features
7//!
8//! - Core data types for sensor readings
9//! - Device information structures
10//! - UUID constants for BLE characteristics
11//! - Error types for data parsing
12//!
13//! # Example
14//!
15//! ```
16//! use aranet_types::{CurrentReading, Status, DeviceType};
17//!
18//! // Types can be used for parsing and serialization
19//! ```
