Function serde_yml::utilities::directory::truncate

pub fn truncate(path: &Path, length: usize) -> Option<String>

Truncates a path to only have a set number of path components.

Will truncate a path to only show the last length components in a path. If a length of 0 is provided, the path will not be truncated. A value will only be returned if the path has been truncated.

Arguments

• path - The path to truncate.
• length - The number of path components to keep.

Returns

• An Option of the truncated path as a string. If the path was not truncated, None is returned.

Example

use serde_yml::utilities::directory::truncate;
use std::path::Path;

let long_path = Path::new("home/user/documents/report/2023/05/27/file.txt");

if let Some(truncated) = truncate(long_path, 3) {
    println!("Truncated path: {}", truncated);
} else {
    println!("Path was not truncated.");
}
