Errors produced while lowering syntax type expressions into HIR.

Variants

ModuleResolve

A module-aware lookup failed at the use site.

Fields

source: ModuleResolveError

span: Span

UnknownTypePath

A type-level path was not found in any namespace valid for that syntax position.

Fields

path: String

span: Span

GenericConstraintMismatch

A natural-number expression referenced a non-Nat generic parameter.

Fields

name: GenericParamName

actual: GenericConstraint

expected: &'static str

span: Span

UnknownGenericParam

A natural-number expression referenced a name that is not a generic parameter.

Fields

name: GenericParamName

span: Span

DuplicateGenericParam

A generic parameter list declared the same name twice.

Fields

name: GenericParamName

first: Span

duplicate: Span

WrongDatetimeArgCount

Datetime<...> has the wrong number of arguments.

Fields

got: usize

span: Span

ExpectedTimeScaleName

Datetime<...> argument was not a bare time-scale name.

Fields

span: Span

UnknownTimeScale

Datetime<...> argument was a bare name, but not a supported time scale.

Fields

name: String

expected: &'static str

span: Span

Trait Implementations

impl Clone for HirLowerError

fn clone(&self) -> HirLowerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HirLowerError

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

Formats the value using the given formatter.

impl Display for HirLowerError

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

Formats the value using the given formatter.

impl Eq for HirLowerError

impl Error for HirLowerError

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 From<HirLowerError> for ExprLowerError

fn from(source: HirLowerError) -> Self

Converts to this type from the input type.

impl PartialEq for HirLowerError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
