**geneos-toolkit** is a Rust library for building Geneos Toolkit compatible
applications. It provides utilities for creating structured Geneos Dataviews,
handling environment variables (including encrypted ones), to simplify
integration development.

## Features

- **Dataviews:** Build and format Geneos Dataviews.
- **Secure Environment Variables:** Retrieve and decrypt environment variables
  seamlessly.

## Installation

Add the following to your `Cargo.toml`:

```toml
[dependencies]
geneos-toolkit = "0.1"  # Use the latest version available
```

## Usage

- Uses the Builder pattern for easy instance initiation.
- The row header is mandatory, set with `set_row_header`.
- Headlines are optional and can be added with `add_headline`.
- At least one value needs to be added to the Dataview, add with `add_value`.
- Values are added in the format `row`, `column`, `value`.
- Rows and Columns are implied in the values and ordered in the Dataview in the
  order they were first introduced.
- Environment variables can be retrieved with `get_var` or `get_secure_var`.
- Secure variables require a key file path.

### Basic Example Dataview

```rust,no_run
use geneos_toolkit::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let clear_env_var = get_var_or("CLEAR_ENV_VAR", "Default Value");
    let secure_env_var = get_secure_var("SECURE_ENV_VAR", "/path/to/key_file")?;

    let dataview = Dataview::builder()
        .set_row_header("Process")
        .add_headline("Hostname", &hostname::get().unwrap_or_default().to_string_lossy())
        .add_headline("Timestamp", &chrono::Utc::now().to_rfc3339())
        .add_headline("Clear Env Var", &clear_env_var)
        .add_headline("Secure Env Var", &secure_env_var)
        .add_value("process1", "Status", "Running")
        .add_value("process1", "CPU", "2.5%")
        .add_value("process1", "Memory", "150MB")
        .build()?;

    println!("{}", dataview);
    Ok(())
}
```
