Why a spec is invalid. Any one invalidates the whole spec. Display is the reason the verifier reports, after the spec’s path.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooLarge

Larger than MAX_SPEC_BYTES.

Byte(u8)

A byte outside printable ASCII, space, tab and LF.

GateName

A gate name outside [A-Za-z0-9][A-Za-z0-9._-]{0,63}.

Fields

line: usize

gate: String

Duplicate

A gate declared on two lines.

Fields

line: usize

gate: String

NoPaths

A gate with no paths.

Fields

line: usize

gate: String

TooManyPaths

A gate with more than MAX_SPEC_PATHS paths.

Fields

line: usize

gate: String

Path

A path that is not a literal, root-relative path.

Fields

line: usize

path: String

problem: PathProblem

TooManyGates

More than MAX_SPEC_GATES gates.

Directive

A line starting with @ that is not @plan-exempt off.

Fields

line: usize

text: String

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for Error
