Enum AppUpdateError 

pub enum AppUpdateError {
    Unsupported,
    Request(String),
    Unverifiable,
    MalformedDigest(String),
    VerificationFailed {
        expected: String,
        actual: String,
    },
}

Failure to start an update operation.

Variants

Unsupported

This platform has no registered installer.

Request(String)

The platform rejected the request before work started.

Unverifiable

The release feed published no digest for this package.

Refused rather than installed: this is an application replacing itself with bytes off the network, and bytes nobody checked are bytes nobody checked whether or not the feed mentioned it. A feed that publishes no digest is a feed to fix, not a check to skip.

MalformedDigest(String)

The release feed published a digest this framework cannot check.

Refused rather than ignored: a digest nobody checks reads as a package that was verified.

VerificationFailed

What arrived is not what the release feed promised.

Fields

expected: String

The digest the release feed published.

actual: String

The digest the bytes that arrived actually have.
