pub enum Error {
    NotPackaged,
    Network(String),
    Velopack(String),
    Applying,
    Prepare(String),
    Taken {
        command: String,
        path: PathBuf,
    },
    CliPath(String),
    Io(Error),
}

What can go wrong with a package’s updates.

Variants

NotPackaged

The app is not running from a package, so there is nothing to update.

Network(String)

The update feed could not be reached.

Velopack(String)

Velopack itself failed.

Applying

An update is being applied already, from another thread.

Prepare(String)

The app’s before_apply refused the update.

Taken

Another program has the command’s name: a file that is not a link, or a link to another program, left alone.

Fields

command: String

path: PathBuf

CliPath(String)

The command line could not be put on or taken off PATH.

Io(Error)

A file could not be read or written.

Trait Implementations

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
