I have JSON data like this
{
"add0" : {
"callcreates" : []
},
"add1" : {
"callcreates" : []
}
//.... 254 other opcodes
}
And I would capture this in a Rust structure. At the top level I have what seems to be a hashmap in Rust. But note the JSON Is not something like
{"opcodes": {"add1": ... "add2: ... }}
where the there is a placeholder for the top-level hashmap.
For the value of the hashmap, I could define a struct.
I have been able to use serde_json::Value
to read in the entire structure, but then I don’t know how to iterate over the top-level JSON keys.
Suggestions?
P.S. http://valve.github.io/blog/2014/08/26/json-serialization-in-rust-part-2/ seems to do what I want except it no longer works playpen
