Crate cu29_traits 

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 }

Structs

CuCompactString

CuError

Common copper Error type.

CuMsgOrigin

Origin metadata captured when a Copper-aware transport receives a remote message.

ObservedWriter

A bincode writer wrapper that reports every encoded byte to Copper’s observation counters.

TaskOutputSpec

Trait to trace back from the CopperList the origin of each message slot.

Enums

UnifiedLogType

Defines the types of what can be logged in the unified logger.

Constants

COMPACT_STRING_CAPACITY

Traits

CopperListTuple

A CopperListTuple needs to be encodable, decodable and fixed size in memory.

CuMsgMetadataTrait

Key metadata piece attached to every message in Copper.

CuPayloadRawBytes

Provides per-output raw payload sizes aligned with ErasedCuStampedDataSet::cumsgs order.

ErasedCuStampedData

A generic trait to expose the generated CuStampedDataSet from the task graph.

ErasedCuStampedDataSet

Trait to get a vector of type-erased CuStampedDataSet This is used for generic serialization of the copperlists

MatchingTasks

Metadata

Represent the minimum set of traits to be usable as Metadata in Copper.

PayloadSchemas

Trait for providing JSON schemas for CopperList payload types.

Reflect

A core trait of bevy_reflect, used for downcasting to concrete types.

WriteStream

Defines a basic write, append only stream trait to be able to log or send serializable objects.

Functions

abort_observed_encode

Aborts any active observed byte counting session.

begin_observed_encode

Starts observed byte counting for the current encode pass.

finish_observed_encode

Ends observed byte counting and returns the total bytes written.

observed_encode_bytes

Returns the number of bytes written so far in the current observed encode pass.

record_observed_encode_bytes

Records bytes written by an observed writer.

with_cause

Creates a CuError with a message and cause in a single call.

Type Aliases

CuResult

Derive Macros

Reflect

The main derive macro used by bevy_reflect for deriving its Reflect trait.
