Enum DAGError 

pub enum DAGError {
    NotFound(Hash),
    VerificationFailed(Hash),
    MissingParents(Vec<Hash>),
    Duplicate(Hash),
}

Errors that can occur during DAG operations.

Variants

NotFound(Hash)

Node not found in the store.

VerificationFailed(Hash)

Node failed verification (CID doesn’t match contents).

MissingParents(Vec<Hash>)

Missing parent nodes (gap in the DAG).

Duplicate(Hash)

Duplicate node (already exists).

Trait Implementations

impl Clone for DAGError

fn clone(&self) -> DAGError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DAGError

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

Formats the value using the given formatter.

impl Display for DAGError

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

Formats the value using the given formatter.

impl Error for DAGError

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<DAGError> for SyncError

fn from(e: DAGError) -> Self

Converts to this type from the input type.

impl PartialEq for DAGError

fn eq(&self, other: &DAGError) -> 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.
