Struct NewPooledTransactionHashes68

Source
pub struct NewPooledTransactionHashes68 {
    pub types: Vec<u8>,
    pub sizes: Vec<usize>,
    pub hashes: Vec<B256>,
}
Expand description

Same as NewPooledTransactionHashes66 but extends that that beside the transaction hashes, the node sends the transaction types and their sizes (as defined in EIP-2718) as well.

Fields§

§types: Vec<u8>

Transaction types for new transactions that have appeared on the network.

§Note on RLP encoding and decoding

In the eth/68 spec this is defined the following way:

  • [type_0: B_1, type_1: B_1, ...]

This would make it seem like the [Encodable] and [Decodable] implementations should directly use a Vec<u8> for encoding and decoding, because it looks like this field should be encoded as a list of bytes.

However, this is implemented in geth as a []byte type, which ends up being encoded as a RLP string, not a RLP list.

Because of this, we do not directly use the Vec<u8> when encoding and decoding, and instead use the [Encodable] and [Decodable] implementations for &[u8] instead, which encodes into a RLP string, and expects an RLP string when decoding.

§sizes: Vec<usize>

Transaction sizes for new transactions that have appeared on the network.

§hashes: Vec<B256>

Transaction hashes for new transactions that have appeared on the network.
