Trait dlopen::symbor::FromRawResult

pub trait FromRawResult where
    Self: Sized, {
    unsafe fn from_raw_result(
        raw: Result<PtrOrNull<'_, ()>, Error>
    ) -> Result<Self, Error>;
}

Allows conversion of raw symbol result into the given symbol.

This trait needs to be implemented by all members of structures that implement the SymBorApi trait. It is used to covert raw result obtained from library into the given object accessible to the user.

Note: Option<T> where T: FromRawResult also implements FromRawResult. This allows you to use options in structures implementing SymBorApi. If the symbol is found, the variable contains Some(symbol), otherwise None.

Note: You probably won’t need to use it directly.
