Struct ProvenanceMismatch 

pub struct ProvenanceMismatch {
    pub rungs: usize,
    pub parameters: usize,
}

A ladder attached to a curve it does not describe.

Unreachable through From<Calibrated>, which builds curve and ladder from one solve. It exists for PinnedCurve::with_provenance, the seam that attaches a ladder obtained elsewhere — where the two can disagree, and where saying so early beats an out-of-bounds read at flip time.

Fields

rungs: usize

Rungs the ladder carries.

parameters: usize

Parameters the curve carries, by the flat walk a risk entry’s node_index counts within.

Trait Implementations

impl Clone for ProvenanceMismatch

fn clone(&self) -> ProvenanceMismatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProvenanceMismatch

impl Debug for ProvenanceMismatch

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

Formats the value using the given formatter.

impl Display for ProvenanceMismatch

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

Formats the value using the given formatter.

impl Eq for ProvenanceMismatch

impl Error for ProvenanceMismatch

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 ProvenanceMismatch

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