Enum EventError 

pub enum EventError {
    MissingReference(Box<ContentId>),
    ReferenceMismatch {
        expected: Box<ContentId>,
        actual: Box<ContentId>,
    },
    Invalid(&'static str),
    DepthMismatch {
        declared: u32,
        implied: u32,
    },
    DepthExceeded(u32),
    Content(Box<ContentError>),
    Elision(VerifyError),
}

Why an event or its elision proof was refused.

Variants

MissingReference(Box<ContentId>)

An event link did not resolve in the caller’s authorized graph.

ReferenceMismatch

A resolver returned an event filed under another event’s address.

Fields

expected: Box<ContentId>

The requested content address.

actual: Box<ContentId>

The returned event’s recomputed address.

Invalid(&'static str)

An origin, operation, or reference relationship violates the contract.

DepthMismatch

The claimed depth disagrees with the resolved derivation inputs.

Fields

declared: u32

The depth supplied by the caller.

implied: u32

The depth recomputed by admission.

DepthExceeded(u32)

Generating from an already generated artifact exceeds the depth bound.

Content(Box<ContentError>)

The addressing crate could not encode an event.

Elision(VerifyError)

Existing kernel verification rejected the addressed source material.

Trait Implementations

impl Debug for EventError

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

Formats the value using the given formatter.

impl Display for EventError

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

Formats the value using the given formatter.

impl Error for EventError

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<Box<ContentError>> for EventError

fn from(source: Box<ContentError>) -> Self

impl From<ContentError> for EventError

fn from(error: ContentError) -> Self

Converts to this type from the input type.

impl From<VerifyError> for EventError

fn from(source: VerifyError) -> Self
