This library abstracts over interacting with the x3270 client. Simply provide the mainframe address and the scripting port for the client in order to immediately interact with the x3270 client programmatically.
ClientAddress struct provides the means to spawn a Client x3270 and a ClientInterface for sending commands to that x3270 instance.
Command implementation utilizes a custom command! macro to simplify and reduce duplicate codeMainframeProvider struct provides functions that utilize one or more lower-level calls to the ClientInterface, allowing for more complex operations.There are currently two levels of abstraction implemented in this library.
To use this lower-level abstraction, simply create an instance of ClientAddress, spawn a Client, and then a ClientInterface. After which you will be able to execute Command instances on the ClientInterface that interact with the spawned x3270 client.
To use this higher-level abstraction, simply create an instance of the ClientInterface as describe above and supply it to the new function of the MainframeProvider. With this struct you will be able to call convenient functions for interacting with the attached Client.
Example coming soon
This crate was inspired by two existing libraries from two different languages. - j3270 - https://github.com/filipesimoes/j3270 - py3270 - https://github.com/py3270/py3270
