What does a method signature look like in a NEAR contract that recieves a JSON Array of objects with undeployed structs?

I am looking to receive Proposal data from a Sputnik v2 DAO Contract. I want to call get_proposals but that returns a json list of the proposals. I am unsure as to what the method signature on the callback function would look like to receive the data. Since sputnik-dao-contract is not a published Rust Crate, I cannot import the Proposal struct and use it to deserialize. What is the best approach to processing the response and getting the Proposal id?

Here is the method I want to call: https://github.com/near-daos/sputnik-dao-contract#view-multiple-proposals

How to I recieve, deserialize and use the response programmatically in Rust?

Solution

  • It turned out the answer was to create a barebones struct that matched the json response. The barebones struct of

    pub struct Proposal {
    pub id: u64,
}

    (from https://github.com/near-daos/sputnik-dao-contract/blob/main/sputnikdao2/src/views.rs#L12) got me what I needed. I added other fields as necessary.
