Error codes for categorizing diagnostic errors.

Variants

E001

Unterminated string literal.

A string was opened with a quote but never closed.

E002

Unexpected character.

A character was encountered that is not valid in this context.

E003

Invalid escape sequence.

An unrecognized escape sequence was used in a string literal. Valid escapes are: \n, \r, \t, \b, \f, \\, \/, \', \", \0, \u{...}.

E004

Invalid unicode escape format.

A unicode escape sequence was malformed. Unicode escapes must use the format \u{XXXX} with 1-6 hexadecimal digits.

E005

Invalid unicode codepoint.

The unicode codepoint is out of range or in the surrogate range. Valid codepoints are 0x0000-0xD7FF and 0xE000-0x10FFFF.

E006

Empty unicode escape.

A unicode escape \u{} was found with no hexadecimal digits.

E100

Unexpected token.

The parser encountered a token it did not expect at this position.

E101

Incomplete input.

The input ended unexpectedly before a complete construct was parsed.

E200

Undefined component reference.

A component was referenced that has not been defined.

E201

Unpaired activate statement.

An activate statement has no matching deactivate.

E202

Unpaired deactivate statement.

A deactivate statement has no matching activate.

E203

Invalid align value for diagram type.

The specified alignment is not valid for this diagram type.

E204

Unknown embed reference.

An embed <name> references an identifier that doesn’t match any namespaced import in the current file.

E300

Undefined type reference.

A type was referenced that has not been defined.

E301

Type override not supported.

Overriding is not supported for this type.

E302

Invalid attribute value.

An attribute value is not valid for the expected type.

E303

Unknown attribute.

An attribute was specified that is not recognized.

E304

Unsupported attribute for shape/type.

The attribute is valid but not supported for this particular shape or type.

E305

Nested diagram not allowed.

A diagram definition was found inside another diagram.

E306

Invalid diagram structure.

The diagram structure is invalid or malformed.

E307

Type mismatch.

A type was used in a context where a different kind of type was expected (e.g., using an Arrow type where a Shape type is required).

E308

Shape does not support nested content.

An attempt was made to add nested content to a shape type that does not support it.

E309

Unresolved embed reference.

An embed <name> references a diagram that could not be resolved.

E400

File not found.

A source file referenced by an import declaration or passed as the root entry point could not be resolved or read.

E401

Circular dependency.

A file appears in its own import chain, forming a cycle.

E402

Invalid import path.

An import path is malformed (e.g., empty).

E403

Invalid namespace derivation.

A namespace identifier could not be derived from the import path (e.g., the path has no file stem or contains non-UTF-8 components).

Implementations

impl ErrorCode

pub fn as_str(&self) -> &'static str

Returns the numeric code as a string (e.g., “E001”).

pub fn description(&self) -> &'static str

Returns a short description of what this error code means.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl Hash for ErrorCode

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 ErrorCode

fn eq(&self, other: &ErrorCode) -> 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.
