Enum SpecError 

pub enum SpecError {
    NoStates,
    DuplicateState(Name),
    DuplicateParam(Name),
    UnknownState(Name),
    UnknownParam(Name),
    WrongKind {
        param: Name,
        declared: ParamKind,
    },
}

Why a spec doesn’t compile.

Variants

NoStates

There are no states.

DuplicateState(Name)

Two states share a name.

DuplicateParam(Name)

Two parameters share a name.

UnknownState(Name)

A name that isn’t a state.

UnknownParam(Name)

A name that isn’t a parameter.

WrongKind

A parameter used as the wrong kind (a float tested as a trigger, …).

Fields

param: Name

The parameter.

declared: ParamKind

Its declared kind.

Trait Implementations

impl Clone for SpecError

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 SpecError

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

Formats the value using the given formatter.

impl Display for SpecError

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

Formats the value using the given formatter.

impl Error for SpecError

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 SpecError

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

Equality operator ==.

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

Inequality operator !=.
