Struct BlobTransactionSidecarEip7594

pub struct BlobTransactionSidecarEip7594 {
    pub blobs: Vec<Blob>,
    pub commitments: Vec<Bytes48>,
    pub cell_proofs: Vec<Bytes48>,
}

This represents a set of blobs, and its corresponding commitments and cell proofs.

This type encodes and decodes the fields without an rlp header.

Fields

blobs: Vec<Blob>

The blob data.

commitments: Vec<Bytes48>

The blob commitments.

cell_proofs: Vec<Bytes48>

List of cell proofs for all blobs in the sidecar, including the proofs for the extension indices, for a total of CELLS_PER_EXT_BLOB proofs per blob (CELLS_PER_EXT_BLOB is the number of cells for an extended blob, defined in the consensus specs)

Implementations

impl BlobTransactionSidecarEip7594

pub const fn new( blobs: Vec<Blob>, commitments: Vec<Bytes48>, cell_proofs: Vec<Bytes48>, ) -> Self

Constructs a new BlobTransactionSidecarEip7594 from a set of blobs, commitments, and cell proofs.

pub fn size(&self) -> usize

Calculates a size heuristic for the in-memory size of the BlobTransactionSidecarEip7594.

pub fn versioned_hashes(&self) -> impl Iterator<Item = B256> + '_

Returns an iterator over the versioned hashes of the commitments.

pub fn match_versioned_hashes<'a>( &'a self, versioned_hashes: &'a [B256], ) -> impl Iterator<Item = (usize, BlobAndProofV2)> + 'a

Matches versioned hashes and returns an iterator of (index, BlobAndProofV2) pairs where index is the position in versioned_hashes that matched the versioned hash in the sidecar.

This is used for the engine_getBlobsV2 RPC endpoint of the engine API

pub fn rlp_encoded_length(&self) -> usize

Calculates the length of the BlobTransactionSidecarEip7594 when encoded as RLP.

pub fn rlp_encode(&self, out: &mut dyn BufMut)

Encodes the BlobTransactionSidecarEip7594 as RLP bytes.

pub fn rlp_decode(buf: &mut &[u8]) -> Result<Self>

Decodes the BlobTransactionSidecarEip7594 from RLP bytes.

impl Decodable7594 for BlobTransactionSidecarEip7594

fn decode_7594(buf: &mut &[u8]) -> Result<Self>

Decode the sidecar according to EIP-7594 rules. First a 1-byte wrapper version (if any), then the body of the sidecar.

impl Default for BlobTransactionSidecarEip7594

fn default() -> BlobTransactionSidecarEip7594

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlobTransactionSidecarEip7594

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for BlobTransactionSidecarEip7594

fn encode(&self, out: &mut dyn BufMut)

Encodes the inner BlobTransactionSidecarEip7594 fields as RLP bytes, without a RLP header.

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

impl Encodable7594 for BlobTransactionSidecarEip7594

fn encode_7594_len(&self) -> usize

The length of the 7594 encoded envelope. This is the length of the wrapper version + the length of the inner encoding.

fn encode_7594(&self, out: &mut dyn BufMut)

Encode the sidecar according to EIP-7594 rules. First a 1-byte wrapper version (if any), then the body of the sidecar.

fn encoded_7594(&self) -> Vec<u8>

Encode the sidecar according to [EIP-7594] rules. First a 1-byte wrapper version (if any), then the body of the sidecar.

impl From<BlobTransactionSidecarEip7594> for BlobTransactionSidecarVariant

fn from(value: BlobTransactionSidecarEip7594) -> Self

Converts to this type from the input type.

impl Hash for BlobTransactionSidecarEip7594

impl PartialEq for BlobTransactionSidecarEip7594

fn eq(&self, other: &BlobTransactionSidecarEip7594) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlobTransactionSidecarEip7594

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
