Enum exonum::runtime::CommonError

#[non_exhaustive]pub enum CommonError {
    NoSuchInterface,
    NoSuchMethod,
    UnauthorizedCaller,
    MalformedArguments,
    MethodRemoved,
    FeatureNotSupported,
}

List of possible common errors.

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.

NoSuchInterface

The interface is absent in the service.

NoSuchMethod

The method is absent in the service.

UnauthorizedCaller

This caller is not authorized to call this method.

MalformedArguments

Malformed arguments for calling a service interface method.

MethodRemoved

Method with provided ID existed in the past, but now is removed.

FeatureNotSupported

Transition between the provided service states is not supported by the runtime.

Methods

impl CommonError

pub fn malformed_arguments(cause: impl Display) -> ExecutionError

Creates a MalformedArguments error with the user-provided error cause. The cause does not need to include the error location; this information is added by the framework automatically.

Trait Implementations

impl Clone for CommonError

fn clone(&self) -> CommonError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for CommonError

impl Debug for CommonError

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

Formats the value using the given formatter.

impl Display for CommonError

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

Formats the value using the given formatter.

impl Eq for CommonError

impl ExecutionFail for CommonError

fn kind(&self) -> ErrorKind

Extracts the error kind.

fn description(&self) -> String

Extracts the human-readable error description.

fn with_description(&self, description: impl Display) -> ExecutionError

Creates an error with an externally provided description. The default implementation takes the description as is; implementations can redefine this to wrap it in an error-specific wrapper.

impl From<CommonError> for ExecutionError

fn from(inner: CommonError) -> Self

Performs the conversion.

impl Hash for CommonError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Ord for CommonError

fn cmp(&self, other: &CommonError) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<CommonError> for CommonError

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<CommonError> for CommonError

fn partial_cmp(&self, other: &CommonError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
