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.

InvalidFormat(String)

Invalid module format or corrupted data

Crypto(String)

Cryptographic operation failure

VerificationFailed

Signature verification failed

Fields

details: String

Details about the failure

Flash(String)

Flash storage operation error

Delta(String)

Delta patch application error

Storage(String)

Storage management error

Io(String)

I/O error (wrapper for std::io::Error in std builds)

InvalidParameter(String)

Invalid parameter provided

CapacityExceeded(String)

Operation would exceed capacity limits

VersionMismatch

Version mismatch or unsupported format

Fields

expected: u16

Expected version

found: u16

Found version

AntiRollback

Anti-rollback protection triggered

Fields

current: u64

Current installed version

attempted: u64

Attempted version

Implementations

impl Error

pub fn invalid_format(msg: impl Into<String>) -> Self

Create a new invalid format error

pub fn crypto(msg: impl Into<String>) -> Self

Create a new crypto error

pub fn flash(msg: impl Into<String>) -> Self

Create a new flash error

pub fn delta(msg: impl Into<String>) -> Self

Create a new delta error

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 From<Error> for Error

Available on crate feature std only.

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for Error
