# Rust client for Solana gRPC interface

This is a sample client for Solana geyser gRPC written in Rust.

This can be used in the following way:

```
$ cargo run --bin client -- --endpoint https://api.rpcpool.com --x-token <token> subscribe --accounts --accounts-account SysvarC1ock11111111111111111111111111111111
