Struct CompositionError 

pub struct CompositionError { /* private fields */ }

How one composition refused, with one required primary issue and every further issue the declaration pass established.

Implementations

impl CompositionError

pub const fn first_issue(&self) -> &CompositionIssue

The first established issue.

pub fn issues(&self) -> impl Iterator<Item = &CompositionIssue>

Every issue this refusal carries, in the order the declaration pass established them; structurally at least one and never truncated.

Trait Implementations

impl Clone for CompositionError

fn clone(&self) -> CompositionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompositionError

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

Formats the value using the given formatter.

impl Display for CompositionError

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

Formats the value using the given formatter.

impl Eq for CompositionError

impl Error for CompositionError

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 CompositionError

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 CompositionError

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

Equality operator ==.

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

Inequality operator !=.

impl Refused for CompositionError

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>

The exact descriptor meaning that repairs the first established composition issue.

const PHASE: Phase = Phase::Capture

The step of the road this refusal is raised at.

const FAMILY: Family = DECLARATION_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.
