Expand description

Why an install did not happen. Every variant is a state the archive or the device is in, so the caller can say something specific without the server sending it a string.

Variants§

§

NotAnApp

The file is not a readable app archive, or breaks the archive format’s rules.

§

InvalidSignature

The archive’s manifest carries no valid publisher signature.

§

FluxEmulatorMissing

A Flux app, which only the Flux emulator can run, and the emulator is not installed.

§

BuiltInApp

The archive claims the app id of an app that ships with the firmware, which no installed app may replace.

§

PublisherMismatch

An app with this id is installed, but from another publisher, so this archive would be a different app taking over its permission grants and stored data rather than an update.

§

AppRunning

The app is already installed and running, so its bundle cannot be replaced.

§

Compatibility(CompatibilityError)

The manifest is valid but incompatible with this KeyOS release.

§

Fs(Error)

The filesystem refused an operation the install needed.

§

Internal

Anything else; the server logs what actually happened.

Trait Implementations§

Source§

impl Archive for InstallError
where CompatibilityError: Archive, Error: Archive,

Source§

type Archived = ArchivedInstallError

The archived representation of this type. Read more
Source§

type Resolver = InstallErrorResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.
Source§

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output. Read more
§

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize. Read more
Source§

impl Clone for InstallError

Source§

fn clone(&self) -> InstallError

Returns a duplicate of the value. Read more
1.0.0§

fn clone_from(&mut self, source: &Self)

where CompatibilityError: Archive, <CompatibilityError as Archive>::Archived: Deserialize<CompatibilityError, __D>, Error: Archive, <Error as Archive>::Archived: Deserialize<Error, __D>,

Source§

fn deserialize( &self, deserializer: &mut __D, ) -> Result<InstallError, <__D as Fallible>::Error>

Deserializes using the given deserializer
Source§

impl<__S: Fallible + ?Sized> Serialize<__S> for InstallError
where CompatibilityError: Serialize<__S>, Error: Serialize<__S>,

Source§

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
