Struct BlobTransactionSidecar

#[repr(C)]
pub struct BlobTransactionSidecar {
    pub blobs: Vec<FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>,
    pub commitments: Vec<FixedBytes<48>>,
    pub proofs: Vec<FixedBytes<48>>,
}

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

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

Fields

blobs: Vec<FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>

The blob data.

commitments: Vec<FixedBytes<48>>

The blob commitments.

proofs: Vec<FixedBytes<48>>

The blob proofs.

Implementations

impl BlobTransactionSidecar

pub fn match_versioned_hashes<'a>( &'a self, versioned_hashes: &'a [FixedBytes<32>], ) -> impl Iterator<Item = (usize, BlobAndProofV1)> + 'a

Matches versioned hashes and returns an iterator of (index, BlobAndProofV1) pairs where index is the position in versioned_hashes that matched the versioned hash in the sidecar.

This is used for the engine_getBlobsV1 RPC endpoint of the engine API

impl BlobTransactionSidecar

pub const fn new( blobs: Vec<FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>, commitments: Vec<FixedBytes<48>>, proofs: Vec<FixedBytes<48>>, ) -> BlobTransactionSidecar

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

pub fn versioned_hashes(&self) -> VersionedHashIter<'_>

Returns an iterator over the versioned hashes of the commitments.

pub fn versioned_hash_for_blob( &self, blob_index: usize, ) -> Option<FixedBytes<32>>

Returns the versioned hash for the blob at the given index, if it exists.

pub fn versioned_hash_index(&self, hash: &FixedBytes<32>) -> Option<usize>

Returns the index of the versioned hash in the commitments vector.

pub fn blob_by_versioned_hash( &self, hash: &FixedBytes<32>, ) -> Option<&FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>

Returns the blob corresponding to the versioned hash, if it exists.

pub const fn size(&self) -> usize

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

pub fn rlp_encoded_length(&self) -> usize

Calculates the length of the BlobTransactionSidecar when encoded as RLP.

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

Encodes the BlobTransactionSidecar as RLP bytes.

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

Decodes the BlobTransactionSidecar from RLP bytes.

Trait Implementations

impl Clone for BlobTransactionSidecar

fn clone(&self) -> BlobTransactionSidecar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlobTransactionSidecar

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decodable for BlobTransactionSidecar

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

Decodes the inner BlobTransactionSidecar fields from RLP bytes, without a RLP header.

impl Decodable7594 for BlobTransactionSidecar

fn decode_7594(buf: &mut &[u8]) -> Result<BlobTransactionSidecar, Error>

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 BlobTransactionSidecar

fn default() -> BlobTransactionSidecar

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlobTransactionSidecar

fn deserialize<__D>( __deserializer: __D, ) -> Result<BlobTransactionSidecar, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for BlobTransactionSidecar

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

Encodes the inner BlobTransactionSidecar 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 BlobTransactionSidecar

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 Hash for BlobTransactionSidecar

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoIterator for BlobTransactionSidecar

type Item = BlobTransactionSidecarItem

The type of the elements being iterated over.

type IntoIter = IntoIter<BlobTransactionSidecarItem>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <BlobTransactionSidecar as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for BlobTransactionSidecar

fn eq(&self, other: &BlobTransactionSidecar) -> 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 BlobTransactionSidecar

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
