The various errors which can be raised by the verifier component, when validating or verifying a light block.

Variants

HeaderFromTheFuture

The header is from the future

Fields of HeaderFromTheFuture

header_time: Time

Time in the header

now: Time

Current time

ImplementationSpecific(String)

Implementation specific error, for the purpose of extensibility

NotEnoughTrust(VotingPowerTally)

Not enough trust because insufficient validators overlap

InsufficientSignersOverlap(VotingPowerTally)

Insufficient signers overlap

DuplicateValidator(ValidatorAddress)

Duplicate validator in commit signatures

InvalidSignature

Invalid commit signature

Fields of InvalidSignature

signature: Vec<u8>

Signature as a byte array

validator: Box<Validator>

Validator which provided the signature

sign_bytes: Vec<u8>

NonIncreasingHeight

Unexpected header of non-increasing height compared to what was expected

Fields of NonIncreasingHeight

got: Height

Actual height of header

expected: Height

Expected minimum height

NonMonotonicBftTime

BFT Time between the trusted state and a header does not increase monotonically

Fields of NonMonotonicBftTime

Implementations

impl VerificationError

pub fn context(self, source: impl Into<BoxError>) -> Context<Self>

Add additional context (i.e. include a source error and capture a backtrace). You can convert the resulting Context into an Error by calling .into().

Trait Implementations

impl Clone for VerificationError

pub fn clone(&self) -> VerificationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerificationError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VerificationError

pub fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for VerificationError

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

Formats the value using the given formatter.

impl Error for VerificationError

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl ErrorExt for VerificationError

pub fn not_enough_trust(&self) -> bool

Whether this error means that the light block cannot be trusted w.r.t. the latest trusted state.

pub fn has_expired(&self) -> bool

Whether this error means that the light block has expired, ie. it's outside of the trusting period.

pub fn is_timeout(&self) -> bool

Whether this error means that a timeout occured when querying a node.

impl PartialEq<VerificationError> for VerificationError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for VerificationError

pub fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for VerificationError
