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.
