pub enum ErrorKind {
    Bind(Option<Endpoint>, Box<dyn StdError + Send>),
    Io(Error),

    Collisions {
        routes: Vec<(Route, Route)>,

}

The error kind that occurred. Returned by Error::kind().

In almost every instance, a launch error occurs because of an I/O error; this is represented by the Io variant. A launch error may also occur because of ill-defined routes that lead to collisions or because a fairing encountered an error; these are represented by the Collision and FailedFairing variants, respectively.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bind(Option<Endpoint>, Box<dyn StdError + Send>)

Binding to the network interface at .0 (if known) failed with .1.

Io(Error)

An I/O error occurred during launch.

Config(Error)

A valid Config could not be extracted from the configured figment.

Collisions

Route or catcher collisions were detected. At least one of routes or catchers is guaranteed to be non-empty.

Fields

routes: Vec<(Route, Route)>

Pairs of colliding routes, if any.

catchers: Vec<(Catcher, Catcher)>

Pairs of colliding catchers, if any.

FailedFairings(Vec<Info>)

Launch fairing(s) failed.

SentinelAborts(Vec<Sentry>)

Sentinels requested abort.

InsecureSecretKey(Profile)

The configuration profile is not debug but no secret key is configured.

Liftoff(Result<Box<Rocket<Ignite>>, Arc<Rocket<Orbit>>>, JoinError)

Liftoff failed. Contains the Rocket instance that failed to shutdown.

Shutdown(Arc<Rocket<Orbit>>)

Shutdown failed. Contains the Rocket instance that failed to shutdown.
