Semantic analysis or binding-safe edit failure.

Variants

UnsupportedLanguage(String)

No four-language frontend is registered.

UnknownBinding(String)

Binding id is absent.

InvalidIdentifier

Replacement is not a valid identifier.

Fields

language: String

identifier: String

CaptureConflict

Rename would capture another binding.

Fields

identifier: String

offset: usize

InvalidRange

A range is reversed, out of bounds, or splits a UTF-8 code point.

Fields

start: usize

end: usize

DestinationInsideRange

A move destination falls strictly inside the moved range.

InvalidEdit

The edited result does not parse cleanly.

InvalidSnapshot(String)

A serialized program snapshot is malformed or inconsistent.

Trait Implementations

impl Eq for ProgramRepresentationError

impl Error for ProgramRepresentationError

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 ProgramRepresentationError

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

Equality operator ==.

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

Inequality operator !=.
