Errors that can occur during OSST operations

Variants

EmptyContributions

No contributions provided

InsufficientContributions

Not enough contributions for threshold

Fields

got: usize

need: usize

DuplicateIndex(u32)

Duplicate custodian index

ZeroChallenge

Challenge hash resulted in zero (astronomically unlikely)

InvalidCommitment

Invalid commitment point (not on curve)

InvalidResponse

Invalid response scalar (not canonical)

LagrangeError

Lagrange computation failed (duplicate indices)

InvalidIndex

Index out of valid range (must be > 0)

Trait Implementations

impl Clone for OsstError

fn clone(&self) -> OsstError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OsstError

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

Formats the value using the given formatter.

impl Display for OsstError

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

Formats the value using the given formatter.

impl Error for OsstError

Available on crate feature std only.

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 PartialEq for OsstError

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