Enum ReceiptEnvelope

#[non_exhaustive]
pub enum ReceiptEnvelope<T = Log> {
    Legacy(ReceiptWithBloom<T>),
    Eip2930(ReceiptWithBloom<T>),
    Eip1559(ReceiptWithBloom<T>),
    Eip4844(ReceiptWithBloom<T>),
    Eip7702(ReceiptWithBloom<T>),
}

Receipt envelope, as defined in EIP-2718.

This enum distinguishes between tagged and untagged legacy receipts, as the in-protocol Merkle tree may commit to EITHER 0-prefixed or raw. Therefore we must ensure that encoding returns the precise byte-array that was decoded, preserving the presence or absence of the TransactionType flag.

Transaction receipt payloads are specified in their respective EIPs.

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.

Legacy(ReceiptWithBloom<T>)

Receipt envelope with no type flag.

Eip2930(ReceiptWithBloom<T>)

Receipt envelope with type flag 1, containing a EIP-2930 receipt.

Eip1559(ReceiptWithBloom<T>)

Receipt envelope with type flag 2, containing a EIP-1559 receipt.

Eip4844(ReceiptWithBloom<T>)

Receipt envelope with type flag 2, containing a EIP-4844 receipt.

Eip7702(ReceiptWithBloom<T>)

Receipt envelope with type flag 4, containing a EIP-7702 receipt.

impl Decodable for ReceiptEnvelope

fn decode(buf: &mut &[u8]) -> Result<ReceiptEnvelope, Error>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.
