Crate cu29_value 

A Copper-oriented value tree used for serialization, logging, and reflection bridges.

The type is a forked/adapted serde-value-style representation with Copper-specific additions such as Value::CuTime.

When the python feature is enabled, this crate also exposes helpers for converting between Value and Python objects through PyO3. Those helpers are used by:

• cu-python-task for runtime prototyping across the Rust/Python boundary
• cu29-export for offline Python log analysis

The Python bridge is intentionally conservative:

• None becomes Value::Unit
• Python lists and tuples become Value::Seq
• Python dicts become Value::Map
• Python integers are accepted up to the 128-bit range
• Python bytes become Value::Bytes

Structs

ValueDeserializer

ValueVisitor

Enums

DeserializerError

Quantity

Copper’s supported physical quantities, independent of scalar width.

QuantityMetadata

A physical quantity associated with a compatible storage unit.

RecordShape

Exported shape of an aggregate.

Scalar

Scalar width and signedness. Integer encoding and endianness come from the codec configuration.

SerializerError

StorageUnit

Physical storage unit, with coherent units identified by their quantity.

TimeStorageUnit

Storage choices for Copper time quantities.

Unexpected

Value

ValueMetadata

Copper-owned logical metadata attached to a value’s schema.
