near-workspaces (Rust) 0.7.0

This release comes with some minor breaking changes, with the main feature here being asynchronous builders for querying data into the chain. Also comes with general fixes for better error reporting that comes from anyhow errors from running sandbox.

Added

• view_* asynchronous builders have been added which provides being able to query from a specific block hash or block height
• {CallTransaction, Transaction}::transact_async for performing transactions without directly having to wait for it complete it on chain
• view_chunk added for querying into chunk related info on the network.
  • Adds Chunk and ChunkHeader type to reference specific chunk info.
• Error::{simple, message, custom} are now public and usable for custom errors

Changed

• Apart of the changes from adding view_* async builders, we have a couple breaking changes to the view_* functions:
  • {Account, Contract, Worker}::view_state moved prefix parameter into builder. i.e.

    worker.view_state("account_id", Some(prefix)).await?;
    // is now
    worker.view_state("account_id")
        .prefix(prefix)
        .await?;
    // if prefix was `None`, then simply delete the None argument.
    

  • view function changed to be a builder, and no longer take in args as a parameter. It instead has been moved to the builder side.
  • Changed Worker::view_latest_block to Worker::view_block as the default behavior is equivalent.
  • operations::Function type no longer takes a lifetime parameter.
  • operations::CallTransaction type takes one less lifetime parameter.
• Worker::call signature changed to be more in line with view_* async builders. It will now return a builder like {Account, Contract}::call
  • This call no longer accepts Contract since that was not as accessible. Instead a InMemorySigner is now required to sign transactions (which can be retrieved from {Account, Contract}::signer or InMemorySigner::{from_secret_key, from_file}).
  • {Account, Contract}::signer now exposed.

Fixed

• Changed the docs to reflect proper size of of rate limits on near.org RPC
• Cached nonces now are per account-id and public-key instead of just public-key
  • this didn't matter if only one KeyPair was being used per account, but could be problematic when there were multiple KeyPairs per account utilizing the same nonces.
• Error message context wasn't being exposed properly by sandbox, so this fixed it
