adxl355

Rust driver for the Analog Devices ADXL355 accelerometer. The crate supports std, no_std, and optional embedded-hal transports while sharing the same register and conversion behavior as the other maintained implementations in this repository.

See the repository root documentation for API status, hardware wiring, and cross-language verification details.

The crates.io distribution name is adxl355-driver; the Rust import remains adxl355 (use adxl355::...).

Typed error handling

The transport trait exposes an associated backend error type. Driver methods return Error<T::Error>, preserving the original transport cause without heap allocation and distinguishing identity, exact-length, lifecycle, configuration, not-ready, timeout, unsupported, and restore failures.

match device.read_raw() {
    Ok(sample) => use_sample(sample),
    Err(Error::Transport(source)) => recover_bus(source),
    Err(Error::InvalidResponseLength { expected, actual, .. }) => {
        report_framing_error(expected, actual)
    }
    Err(Error::InvalidState { required }) => report_state_requirement(required),
    Err(Error::Restore(source)) => report_restore_failure(source),
    Err(other) => report_driver_error(other),
}

This associated-error API is an alpha-stage breaking change from the earlier string-like/coarse Error::Bus model. Custom transports implement type Error = MyBackendError and return that cause directly.
