Crate solana_write_account 

Helper smart contract and library functions to support calling Solana programs with instruction data read from an account.

Solana limits transaction size to at most 1232 bytes. This includes all accounts participating in the transaction as well as all the instruction data. Unfortunately, some programs may need to encode instructions which don’t fit in that limit.

To address this, Solana program may support reading instruction data from an account. This library provides a helper Solana program which allows populating the account with overlong instruction data, client helper functions for invoking program with instruction stored in an account (when built with client feature) and helper [entrypoint] module for Solana programs which want to support reading instruction data from an account (when built with lib feature).

The account data must be a length-prefixed slice of bytes. In other words, borsh-serialised Vec<u8>. The account may contain trailing bytes which are ignored.

This module provides types to help use this feature of the Solana IBC contract. [Accounts] is used to add the account with instruction data to an instruction and [Instruction] constructs an empty instruction data to call the contract with.
