Expand description
An HTTP typed header for the graph-indexed
header.
The graph-indexed
header contains a JSON-encoded BlockInfo
struct indicating the latest
indexed block information.
§Using the headers::HeaderMapExt
extension trait
use headers::HeaderMapExt as _;
use thegraph_headers::graph_indexed::{GraphIndexed, HEADER_NAME};
let mut header_map = http::HeaderMap::new();
// Insert a `graph-indexed` HTTP header
header_map.typed_insert(GraphIndexed(value));
// Get the `graph-indexed` HTTP header by name
let header_by_name = header_map.get(HEADER_NAME);
assert!(header_by_name.is_some());
// Get the `graph-indexed` HTTP header by type
let header_typed = header_map.typed_get::<GraphIndexed>();
assert!(matches!(header_typed, Some(GraphIndexed(..))));
