Function write_to_file

pub fn write_to_file(file_path: &str, content: &[u8]) -> Result<(), Error>

Writes the provided content to a file at the specified file_path. If the file does not exist, it will be created. If the file exists, the content will be appended to it.

Parameters

• file_path: The path to the file where the content will be written.
• content: A byte slice (&[u8]) containing the content to be written to the file.

Returns

• Result<(), Error>:
  • Ok(()): If the content was successfully written to the file.
  • Err(Error): If there was an error during file creation or writing.

Errors

• If the file cannot be created or opened for writing, an error will be returned. This can happen if:
  • There is a problem with the file path (e.g., invalid or inaccessible path).
  • There are I/O issues when writing to the file.

Notes

• The function first ensures that the parent directory of the file exists. If it doesn’t, it attempts to create the entire directory structure using create_dir_all.
• The file is opened using OpenOptions with the following options:
  • write(true): Open the file for writing.
  • append(true): If the file exists, append the content to the end of the file.
  • create(true): If the file doesn’t exist, create it.
