=== Assistant: Below is an implementation that satisfies all test cases. ===
Below is an implementation that satisfies all test cases.
It trims the whole input, validates non-emptiness, splits by newline, trims each line, filters out empty results, and returns an error when no valid entries remain.

<syntaxhighlight lang="rust">use error_stack::{Report, ResultExt};
use crate::ApplicationError;

pub fn get_vec_string(text: &str) -> Result<Vec<String>, Report<ApplicationError>> {
let trimmed = text.trim();

if trimmed.is_empty() {
return Err(Report::new(ApplicationError::ParameterWrong));
}

let items: Vec<String> = trimmed
.lines()
.map(|line| line.trim())
.filter(|line| !line.is_empty())
.map(|s| s.to_string())
.collect();

if items.is_empty() {
return Err(Report::new(ApplicationError::ParameterWrong));
}

Ok(items)
}

</syntaxhighlight>

This implementation matches all behaviors expected by the unit tests.
