// This example shows additional functionality of the "interactive-clap" macro for parsing command-line data into a structure using the macro's flatten attributes.
|
|
|
|
// 1) build an example: cargo build --example struct_with_flatten
|
|
// 2) go to the `examples` folder: cd target/debug/examples
|
|
// 3) run an example: ./struct_with_flatten (without parameters) => entered interactive mode
|
|
// ./struct_with_flatten QWERTY 18 => account: CliAccount { social_db_folder: None, account: Some(CliSender { sender_account_id: Some("QWERTY"), age: Some(18) }) }
|
|
// To learn more about the parameters, use "help" flag: ./struct_with_flatten --help
