Crate kudu_esr 

This crate provides tools to create and sign EOS Signing Requests (ESR).

Feature flags

• float128: add support for a native float128 type. This currently needs a nightly Rust version as f128 support is still experimental. If this is not active, the Float128 will still be available but as a [u8; 16] wrapper.

TODO / FIXME

API DESIGN

• use typestates to encode the different possible states of a transaction see: https://cliffle.com/blog/rust-typestate/

• check this for example of API:

  const expireSeconds = 300
  const abiResponse = await jungle4.v1.chain.get_abi('eosio.token')
  const info = await jungle4.v1.chain.get_info()
  const header = info.getTransactionHeader(expireSeconds)
  const action = Action.from(
      {
          authorization: [
              {
                  actor: 'corecorecore',
                  permission: 'active',
              },
          ],
          account: 'eosio.token',
          name: 'transfer',
          data: {
              from: 'corecorecore',
              to: 'teamgreymass',
              quantity: '0.0042 EOS',
              memo: '',
          },
      },
      abiResponse.abi
  )
  const transaction = Transaction.from({
      ...header,
      actions: [action],
  })
  const result = await jungle4.v1.chain.compute_transaction(transaction)

• do we want ABIProvider to be a member of SigningRequest, or should we just pass it every time we need it?

  • having it as member would allow us to have de/serialization to a JSON value with decoded data

CORRECTNESS / TESTING

• look at https://github.com/wharfkit/signing-request/blob/master/src/abi.ts

• check for more tests in:

  • https://github.com/wharfkit/signing-request/
  • https://github.com/wharfkit/protocol-esr/

• also check here: https://github.com/greymass/eosio-signing-request-demo/blob/master/examples/resolve.js

MISSING FEATURES

• need to implement the identity signing request type

MISC

• report bug for wharfkit.request creation: duplicate context_free_actions, missing context_free_data https://github.com/wharfkit/signing-request/blob/master/src/signing-request.ts#L410 see tx def: https://docs.eosnetwork.com/docs/latest/advanced-topics/transactions-protocol/
