Enum Error 

#[non_exhaustive]
pub enum Error {
    Image(PrepareError),
    UnknownFraming,
    Ambiguous,
}

Why an input could not be loaded as a unique validated image.

Hosts must keep a wildcard arm; the set of variants may grow.

fn f(e: mediatek_optical::envelope::Error) -> u8 { match e { mediatek_optical::envelope::Error::Image { .. } => 0, mediatek_optical::envelope::Error::UnknownFraming { .. } => 1, mediatek_optical::envelope::Error::Ambiguous { .. } => 2, } }

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Image(PrepareError)

Size, integrity, chip or stored-image checks failed.

UnknownFraming

Neither representation has a supported boot banner.

Ambiguous

Both representations validated; choosing either would be a guess.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CodedError for Error

Available on crate features enc and image only.

fn code(&self) -> &'static str

Stable identifier, such as mediatek.receiver.changed.

fn kind(&self) -> IssueKind

Protocol-neutral host guidance category; never derives from diagnostic prose.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Error
