Struct alloy_eips::eip4844::builder::PartialSidecar

pub struct PartialSidecar { /* private fields */ }

A builder for creating a BlobTransactionSidecar.

Implementations

impl PartialSidecar

pub fn new() -> Self

Create a new builder, and push an empty blob to it. This is the default constructor, and allocates space for 2 blobs (256 KiB). If you want to preallocate a specific number of blobs, use PartialSidecar::with_capacity.

pub fn with_capacity(capacity: usize) -> Self

Create a new builder, preallocating room for capacity blobs, and push an empty blob to it.

pub fn blobs(&self) -> &[Blob]

Get a reference to the blobs currently in the builder.

pub const fn len(&self) -> usize

Calculate the length of used field elements IN BYTES in the builder.

This is always strictly greater than the number of bytes that have been ingested.

pub const fn is_empty(&self) -> bool

Check if the builder is empty.

pub fn alloc_fes(&mut self, required_fe: usize)

Allocate enough space for the required number of new field elements.

pub fn ingest_valid_fe(&mut self, data: WholeFe<'_>)

Ingest a field element into the current blobs.

pub fn ingest_partial_fe(&mut self, data: &[u8])

Ingest a partial FE into the current blobs.

Panics

If the data is >=32 bytes. Or if there are not enough free FEs to encode the data.
