pub fn read_from_file<T>(file_path: &str) -> Result<T, Box<dyn Error>>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 typeT.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_pathdoes not exist. - There is an I/O error while reading the file.
- The content of the file cannot be converted to type
T.
- The file at
§Notes
- The function assumes that the content of the file can be represented as a byte vector (
Vec<u8>), which is then passed toT::fromfor conversion.
