Required Methods

fn ok_or_err<S>(self, name: impl Into<String>) -> Result<Self::Value, Error<S>>where
    S: Scope,

Map None condition to an error message with a const name of some value that is expected not to be None.

fn ok_or_err_else<S, N, F>(
    self,
    name_factory: F
) -> Result<Self::Value, Error<S>>where
    S: Scope,
    N: Into<String>,
    F: FnOnce() -> N,

Map None condition to an error message with a function generatred name of some value that is expected not to be None.
