The reason for a transfer of DPP responsibility.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sale

Product sold to a new economic operator for market placement.

Return

Product returned to the supply chain (e.g. customer return).

Remanufacturing

Product sent for remanufacturing.

Repurposing

Product adapted for a different purpose.

PreparationForReuse

Product prepared for resale as second-hand.

PreparationForRepurposing

Waste product prepared so that it can serve a different purpose.

Distinct from Self::Repurposing, and the difference is the input, not the outcome: Reg. (EU) 2023/1542 Art. 3(30) defines this over “a waste battery, or parts thereof”, while Art. 3(31) defines repurposing over “a battery, that is not a waste battery”. Art. 77(7) names all four second-life operations, and this one was the only one of them this enum could not express.

WasteHandover

The battery has become waste, and responsibility moves with it.

✅ COMPLIANCE-PIN: EU 2023/1542, Art. 77(7) second subparagraph (OJ L 191, 28.7.2023, p. 73) — responsibility passes to the producer, to the producer responsibility organisation where one is appointed under Art. 57(1), or to the waste management operator selected under Art. 57(8). The same subparagraph mandates no new passport, which is what distinguishes this handover from the four second-life operations.

Deliberately not folded into SecondLifeOperation: that is a different vocabulary. Those four describe second-life processing that produces a new unit, whereas this records a waste handover on a record that continues. Folding them would let the lineage-consent rule match a waste handover against a derivation edge, which is not the consent that rule is looking for.

Import

Product imported into the EU by a new importer.

InsolvencySuccession

Original operator became insolvent; responsibilities assumed by successor.

Implementations

impl TransferReason

pub const ALL: &'static [Self]

Every reason this build models, for exhaustive iteration.

TransferReason is #[non_exhaustive], so a consumer outside this crate cannot enumerate it, and one publishing an API description has to. See crate::seal::SealFormat::ALL for the same contract: a reason added later is deliberately not covered until it is added here.

pub fn wire_str(&self) -> &'static str

The stable wire form, for payloads that carry the reason as a string.

Spelled out rather than derived from Serialize so that renaming a variant cannot silently change what a registry receives.

Trait Implementations

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)
