Function check_diary_path_exists

pub fn check_diary_path_exists(
    full_diary_path: &PathBuf,
) -> Result<(), Box<dyn Error>>

Verifies whether a diary file exists at the specified path.

This function checks if the file at the given path exists on the filesystem. It’s used to determine whether to create a new diary file with a template or append to an existing one.

Arguments

• full_diary_path - Path to the diary file to check

Returns

• Ok(()) - File exists at the specified path
• Err(Box<dyn Error>) - File does not exist at the specified path

Errors

Returns an error if:

• The file does not exist on the filesystem
• The path cannot be accessed due to permission issues
• The path represents a directory instead of a file

Examples

use rusty_commit_saver::vim_commit::check_diary_path_exists;
use std::path::PathBuf;
use std::fs::File;

// Create a temporary test file
let test_file = PathBuf::from("/tmp/test_diary.md");
File::create(&test_file).unwrap();

// File exists - returns Ok
assert!(check_diary_path_exists(&test_file).is_ok());

// File doesn't exist - returns Err
let missing_file = PathBuf::from("/tmp/nonexistent.md");
assert!(check_diary_path_exists(&missing_file).is_err());
