Struct GetBlockHeaders

Source
pub struct GetBlockHeaders {
    pub start_block: BlockHashOrNumber,
    pub limit: u64,
    pub skip: u32,
    pub direction: HeadersDirection,
}
Expand description

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 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 headers, starting from start_block and returning at most limit headers.

§direction: HeadersDirection

The direction in which the headers should be returned in.
