Struct BlobsBundleV2 

pub struct BlobsBundleV2 {
    pub commitments: Vec<FixedBytes<48>>,
    pub proofs: Vec<FixedBytes<48>>,
    pub blobs: Vec<FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>,
}

Available on crate feature rpc only.

This includes all bundled blob related data of an executed payload.

Fields

commitments: Vec<FixedBytes<48>>

All commitments in the bundle.

proofs: Vec<FixedBytes<48>>

All cell proofs in the bundle.

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

All blobs in the bundle.

Implementations

impl BlobsBundleV2

pub fn new( sidecars: impl IntoIterator<Item = BlobTransactionSidecarEip7594>, ) -> BlobsBundleV2

Creates a new blob bundle from the given sidecars.

This folds the sidecar fields into single commit, proof, and blob vectors.

pub fn empty() -> BlobsBundleV2

Returns a new empty blobs bundle.

This is useful for the opstack engine API that expects an empty bundle as part of the payload for API compatibility reasons.

pub fn versioned_hashes(&self) -> Vec<FixedBytes<32>>

Computes the versioned hashes from the KZG commitments.

pub fn take( &mut self, len: usize, ) -> (Vec<FixedBytes<48>>, Vec<FixedBytes<48>>, Vec<FixedBytes<alloy_eips::::eip4844::Blob::{constant#0}>>)

Take len blob data from the bundle.

Note this will take len * CELLS_PER_EXT_BLOB proofs.

Panics

If len is more than the blobs bundle len.

pub fn pop_sidecar(&mut self, len: usize) -> BlobTransactionSidecarEip7594

Returns the sidecar from the bundle

Panics

If len is more than the blobs bundle len.

pub fn try_into_sidecar( self, ) -> Result<BlobTransactionSidecarEip7594, ValueError<BlobsBundleV2>>

Available on crate feature kzg only.

Converts this bundle into a single BlobTransactionSidecarEip7594.

Returns an error if the bundle doesn’t contain the correct number of cell proofs (expected blobs.len() * CELLS_PER_EXT_BLOB) or if the commitments length doesn’t match the blobs length.

Returns an empty BlobTransactionSidecarEip7594 if the bundle is empty.

pub fn try_into_v1(self) -> Result<BlobsBundleV1, Error>

Available on crate feature kzg only.

Converts this V2 bundle into a BlobsBundleV1 by computing EIP-4844 blob proofs.

This uses the default KZG settings. See Self::try_into_v1_with_settings for custom settings.

Errors

Returns an error if KZG proof computation fails.

pub fn try_into_v1_with_settings( self, settings: &KZGSettings, ) -> Result<BlobsBundleV1, Error>

Available on crate feature kzg only.

Converts this V2 bundle into a BlobsBundleV1 by computing EIP-4844 blob proofs using the provided KZG settings.

This recomputes the blob proofs from the blobs and commitments. The cell proofs from V2 are discarded as they are not used in V1.

Errors

Returns an error if KZG proof computation fails.
