Enum DiffEngineError 

pub enum DiffEngineError {
    Empty,
    Unsupported {
        n: usize,
    },
}

D.8.a: errors compute_diff returns for unsupported participant counts. v1’s cap (N ≤ 3) is enforced here, not in the descriptor / subsystem layer — moving the cap means extending the Unsupported arm with new computation.

Trait Implementations

impl Clone for DiffEngineError

fn clone(&self) -> DiffEngineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffEngineError

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

Formats the value using the given formatter.

impl Display for DiffEngineError

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

Formats the value using the given formatter.

impl Eq for DiffEngineError

impl Error for DiffEngineError

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<DiffEngineError> for MembershipError

fn from(source: DiffEngineError) -> Self

Converts to this type from the input type.

impl PartialEq for DiffEngineError

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

Equality operator ==.

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

Inequality operator !=.
