Struct ethp2p::GetBlockHeaders

pub struct GetBlockHeaders {
    pub start_block: BlockHashOrNumber,
    pub limit: u64,
    pub skip: u32,
    pub reverse: bool,
}

A request for a peer to return block headers starting at the requested block. The peer must return at most limit headers. If the reverse field is true, the headers will be returned starting at start_block, traversing towards the genesis block. Otherwise, headers will be returned starting at start_block, traversing towards the latest block.

If the skip field is non-zero, the peer must skip that amount of headers in the the direction specified by reverse.

Fields

start_block: BlockHashOrNumber

The block number or hash that the peer should start returning headers from.

limit: u64

The maximum number of headers to return.

skip: u32

The number of blocks that the node should skip while traversing and returning headers. A skip value of zero denotes that the peer should return contiguous heaaders, starting from start_block and returning at most limit headers.

reverse: bool

Whether or not the headers should be returned in reverse order.

impl PartialEq<GetBlockHeaders> for GetBlockHeaders

fn eq(&self, other: &GetBlockHeaders) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
