Enum DeclarationError 

pub enum DeclarationError {
    EmptyNamespace,
    EmptyStem,
    SpellingNotAnIdentifier,
    PathSegmentsAbsent,
    PathSegmentsUnbounded,
}

A support-declaration refusal.

Variants

EmptyNamespace

A name has no owner.

EmptyStem

SpellingNotAnIdentifier

A spelling is not one Rust identifier.

PathSegmentsAbsent

A path has no segment after its root.

PathSegmentsUnbounded

A path exceeds its segment bound.

Implementations

impl DeclarationError

pub fn canonical_bytes(self) -> Vec<u8>

Returns canonical bytes.

pub fn encode_into(self, into: &mut Vec<u8>)

Appends canonical bytes.

impl DeclarationError

pub const fn slot(self) -> u8

Trait Implementations

impl Clone for DeclarationError

fn clone(&self) -> DeclarationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DeclarationError

impl Debug for DeclarationError

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

Formats the value using the given formatter.

impl Eq for DeclarationError

impl Error for DeclarationError

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 DeclarationError

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 DeclarationError

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

Equality operator ==.

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

Inequality operator !=.

impl Refused for DeclarationError

const PHASE: Phase = Phase::Capture

The step of the road this refusal is raised at.

const FAMILY: Family = SUPPORT_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

fn body(&self) -> LineBody

What the summary line is a summary of.

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