Expand description

The kind of launch error that occurred.

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. The Unknown variant captures all other kinds of launch errors.

Variants§

§

Bind(Error)

Binding to the provided address/port failed.

§

Io(Error)

An I/O error occurred during launch.

§

Collision(Vec<(Route, Route)>)

Route collisions were detected.

§

FailedFairings(Vec<&'static str>)

A launch fairing reported an error.

§

Unknown(Box<dyn Error + Send + Sync>)

An otherwise uncategorized error occurred during launch.
