Enum Error 

pub enum Error<E> {
    Bundle(Error),
    Storage(Error<E>),
    VerifyFailed,
}

Why an install was refused or failed.

Generic over the device error, unlike bundle::Error, which is why the two are separate types: a host that only ever builds bundles would otherwise have to name a block-device error it does not have.

Variants

Bundle(Error)

The bundle was rejected before anything was written.

Storage(Error<E>)

The card or the filesystem failed.

VerifyFailed

A file read back after writing did not match what was written.

Implementations

impl<E> Error<E>

pub fn http_status(&self) -> u16

The HTTP status to answer this with, for a device that took the bundle over HTTP.

A rejected bundle is the sender’s fault and a card that failed mid-write is not, and answering the same to both sends whoever is updating to look at the wrong thing.

Trait Implementations

impl<E: Debug> Debug for Error<E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E: Debug> Display for Error<E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E: Debug> Error for Error<E>

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

Returns the lower-level source of this error, if any.

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<E> From<Error<E>> for Error<E>

fn from(error: Error<E>) -> Error<E>

Converts to this type from the input type.

impl<E> From<Error> for Error<E>

fn from(error: Error) -> Error<E>

Converts to this type from the input type.
