Struct BlockHeaderByNumberRequest 

pub struct BlockHeaderByNumberRequest {
    pub block_num: Option<u32>,
    pub include_mmr_proof: Option<bool>,
}

Returns the block header corresponding to the requested block number, as well as the merkle path and current forest which validate the block’s inclusion in the chain.

The Merkle path is an MMR proof for the block’s leaf, based on the current chain length.

Fields

block_num: Option<u32>

The target block height, defaults to latest if not provided.

include_mmr_proof: Option<bool>

Whether or not to return authentication data for the block header.

Implementations

impl BlockHeaderByNumberRequest

pub fn block_num(&self) -> u32

Returns the value of block_num, or the default value if block_num is unset.

pub fn include_mmr_proof(&self) -> bool

Returns the value of include_mmr_proof, or the default value if include_mmr_proof is unset.

impl Message for BlockHeaderByNumberRequest

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl PartialEq for BlockHeaderByNumberRequest

fn eq(&self, other: &BlockHeaderByNumberRequest) -> 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.
