Trait rocket::outcome::IntoOutcome

pub trait IntoOutcome<S, E, F> {
    type Failure: Sized;
    type Forward: Sized;

    // Required methods
    fn into_outcome(self, failure: Self::Failure) -> Outcome<S, E, F>;
    fn or_forward(self, forward: Self::Forward) -> Outcome<S, E, F>;
}

Conversion trait from some type into an Outcome type.

Required Associated Types

type Failure: Sized

The type to use when returning an Outcome::Failure.

type Forward: Sized

The type to use when returning an Outcome::Forward.

Required Methods

fn into_outcome(self, failure: Self::Failure) -> Outcome<S, E, F>

Converts self into an Outcome. If self represents a success, an Outcome::Success is returned. Otherwise, an Outcome::Failure is returned with failure as the inner value.

fn or_forward(self, forward: Self::Forward) -> Outcome<S, E, F>

Converts self into an Outcome. If self represents a success, an Outcome::Success is returned. Otherwise, an Outcome::Forward is returned with forward as the inner value.
