Solana Geyser Plugin Interface

This crate enables a plugin to be added into the Solana Validator runtime to take actions at the time of account updates or block and transaction processing; for example, saving the account state to an external database. The plugin must implement the GeyserPlugin trait. Please see the details of the geyser_plugin_interface.rs for the interface definition.

The plugin should produce a cdylib dynamic library, which must expose a C function _create_plugin() that instantiates the implementation of the interface.

The https://github.com/solana-labs/solana-accountsdb-plugin-postgres repository provides an example of how to create a plugin which saves the accounts data into an external PostgreSQL database.

More information about Solana is available in the Solana documentation.
