Function async_read_from_file

Source 
pub async fn async_read_from_file<T>(
    file_path: &str,
) -> Result<T, Box<dyn Error>>
where
    T: From<Vec<u8>>,
Expand description

Reads the content of a file at the specified file_path and converts it to the type T. The conversion is done by using the From<Vec<u8>> trait, which allows the file content (read as raw bytes) to be converted into a type T.

§Parameters

  • file_path: The path to the file that will be read.

§Returns

  • Result<T, Box<dyn std::error::Error>>:
    • Ok(T): The file was read successfully and converted to the specified type T.
    • Err(Box<dyn std::error::Error>): An error occurred while opening or reading the file. This will contain any errors encountered during the file operations, including I/O or conversion errors.

§Errors

  • This function may return an error if:
    • The file at file_path does not exist.
    • There is an I/O error while reading the file.
    • The content of the file cannot be converted to type T.

§Notes

  • The function assumes that the content of the file can be represented as a byte vector (Vec<u8>), which is then passed to T::from for conversion.
