This crate enables an 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 detail 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 databases.
More information about Solana is available in the Solana documentation.
