Struct BlockBuilder 

pub struct BlockBuilder { /* private fields */ }

Builder for creating blocks with custom CID settings.

Use this when you need to specify a custom hash algorithm, CID version, or codec.

Example

use ipfrs_core::{Block, HashAlgorithm, cid::codec};
use bytes::Bytes;

let block = Block::builder()
    .hash_algorithm(HashAlgorithm::Sha3_256)
    .codec(codec::DAG_CBOR)
    .build(Bytes::from_static(b"data"))
    .unwrap();

Implementations

impl BlockBuilder

pub fn new() -> Self

Creates a new BlockBuilder with default settings.

Uses SHA2-256 hash algorithm and CIDv1 by default.

pub fn hash_algorithm(self, algorithm: HashAlgorithm) -> Self

Set the hash algorithm to use

pub fn cid_version(self, version: Version) -> Self

Set the CID version

pub fn codec(self, codec: u64) -> Self

Set the codec

pub fn build(self, data: Bytes) -> Result<Block>

Build a block from data

pub fn build_from_slice(self, data: &[u8]) -> Result<Block>

Build a block from data slice (convenience method)
