Struct ExplanationError 

pub struct ExplanationError { /* private fields */ }

How the explanation protocol says no.

Coverage issues are independent and co-establishable — several questions may stand unanswered while another is doubled — so the body carries every issue the pass established rather than electing a primary one, and says so where it kept only what fits.

Implementations

impl ExplanationError

pub fn of(issue: ExplanationIssue) -> Self

The refusal one established issue makes.

pub fn over(first: ExplanationIssue, rest: Vec<ExplanationIssue>) -> Self

The refusal a pass whose checks co-establish makes.

The caller arrives holding every issue its pass established, so the posture the body writes is about the REPORT and never about the pass: where the issues fit it carries all of them, and where they do not it carries what fits and counts the rest.

pub fn bounded(overflow: Overflow) -> Self

The refusal a seat bound makes, out of the two counts the overflow already carries.

pub fn first_issue(&self) -> &ExplanationIssue

The first issue the pass established, which every refusal has.

pub fn issues(&self) -> &NonEmpty<ExplanationIssue, EXPLANATION_ISSUE_LIMIT>

Every issue this refusal carries, in the order the pass established them; structurally at least one.

pub const fn capping(&self) -> Capping

Whether this refusal carries every issue its pass established.

Trait Implementations

impl Clone for ExplanationError

fn clone(&self) -> ExplanationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExplanationError

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

Formats the value using the given formatter.

impl Display for ExplanationError

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

Formats the value using the given formatter.

impl Eq for ExplanationError

impl Error for ExplanationError

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 Hash for ExplanationError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExplanationError

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

Equality operator ==.

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

Inequality operator !=.

impl Refused for ExplanationError

fn related(&self) -> Vec<Vec<u8>>

The issues established beyond the primary cause; the primary is the summary’s own subject, never a member of its related set.

fn repairs(&self) -> Bounded<Repair, REPAIR_LIMIT>

This home declares no repair of its own.

Every issue above is about which questions the caller answered, so the repair is that answer sheet; a sentence composed here would be this compiler citing a fact nobody declared.

const PHASE: Phase = Phase::Explanation

The step of the road this refusal is raised at.

const FAMILY: Family = EXPLANATION_FAMILY

The family whose issue space this refusal’s related identities derive in.

fn class(&self) -> RefusalClass

Which class of refusal the summary line opens with.

fn first(&self) -> String

How the first established issue reads for a person.

fn observed(&self) -> Observed

How what was observed differs from the expected contract, read off that same first issue.

fn body(&self) -> LineBody

What the summary line is a summary of.
