Struct common_types::views::HeaderView

pub struct HeaderView<'a> { /* private fields */ }

View onto block header rlp.

Implementations

impl<'a> HeaderView<'a>

pub fn new(rlp: ViewRlp<'a>) -> HeaderView<'a>

Creates a new Header view from valid ViewRlp Use the view! macro to create this view in order to capture debugging info.

Example

#[macro_use]
extern crate common_types as types;

use types::views::{HeaderView};

fn main() {
let bytes : &[u8] = &[];
let tx_view = view!(HeaderView, bytes);
}

pub fn hash(&self) -> H256

Returns header hash.

pub fn rlp(&self) -> &ViewRlp<'a>

Returns raw rlp.

pub fn parent_hash(&self) -> H256

Returns parent hash.

pub fn uncles_hash(&self) -> H256

Returns uncles hash.

pub fn author(&self) -> Address

Returns author.

pub fn state_root(&self) -> H256

Returns state root.

pub fn transactions_root(&self) -> H256

Returns transactions root.

pub fn receipts_root(&self) -> H256

Returns block receipts root.

pub fn log_bloom(&self) -> Bloom

Returns block log bloom.

pub fn difficulty(&self) -> U256

Returns block difficulty.

pub fn number(&self) -> BlockNumber

Returns block number.

pub fn gas_limit(&self) -> U256

Returns block gas limit.

pub fn gas_used(&self) -> U256

Returns block gas used.

pub fn timestamp(&self) -> u64

Returns timestamp.

pub fn extra_data(&self) -> Bytes

Returns block extra data.

pub fn seal(&self, eip1559: bool) -> Vec<Bytes>

Returns a vector of post-RLP-encoded seal fields. If eip1559 is true, seal contains also base_fee_per_gas. Otherwise, it contains only seal fields.

pub fn base_fee(&self) -> U256

Returns block base fee. Should be called only for EIP1559 headers. If called for non EIP1559 header, returns garbage

pub fn decode_seal(&self, eip1559: bool) -> Result<Vec<Bytes>, DecoderError>

Returns a vector of seal fields (RLP-decoded). If eip1559 is true, seal contains also base_fee_per_gas. Otherwise, it contains only seal fields.
