Common copper traits and types for robotics systems.

This crate is no_std compatible by default. Enable the "std" feature for additional functionality like implementing std::error::Error for CuError and the new_with_cause method that accepts types implementing std::error::Error.

Features

• std (default): Enables standard library support
  • Implements std::error::Error for CuError
  • Adds CuError::new_with_cause() method for interop with std error types

no_std Usage

To use without the standard library:

[dependencies]
cu29-traits = { version = "0.9", default-features = false }

cu29-traits

Common traits and shared types used across Copper runtime and components.

This crate is designed to be usable both inside and outside Copper. It provides core result/error types, logging stream traits, and common robotics-facing interfaces that help decouple components.

Features

• std (default): enables std::error::Error integration.
• defmt: enables embedded defmt support.

no_std

cu29-traits supports no_std by disabling default features.
