Function async_write_to_file

Source
pub async fn async_write_to_file(
    file_path: &str,
    content: &[u8],
) -> Result<(), Error>
Expand description

Writes the provided content to a file at the specified file_path asynchronously.

  • 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: Ok(()) if the content was successfully written to the file, or an Err with the error details.

§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.
