Why a fragment could not be typeset.

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.

Tex

TeX reported an error, which ends the run.

Fields

message: String

TeX’s error message, such as Undefined control sequence.

line: Option<u32>

1 based line of the caller’s tex TeX was reading, None past its end.

span: Option<ByteSpan>

Byte span of the caller’s tex holding the token TeX read last.

Sandbox

The sandbox rejected a command, such as a math shift that leaves the math or a file access.

Fields

message: String

What was rejected.

span: Option<ByteSpan>

Byte span of the caller’s tex holding the rejected token.

Budget

The fragment ran past Options::op_budget, it is too complex or does not terminate.

NodeLimit

The fragment lowers to more than Options::max_nodes IR nodes.

Fields

limit: usize

The cap that was hit.

Font

A font the format needs could not be loaded.

Fields

spec: String

The font’s \font spec.

error: FontError

Why it could not be loaded.

Format

The format’s state cannot run fragments.

Fields

message: String

Why it cannot.

TooLong

The fragment is longer than a span can index.

NoOutput

The run finished without building the fragment’s box.

Lowering

The laid out fragment broke an IR invariant, a bug in the lowering.

Fields

message: String

The broken invariant.

Trait Implementations

impl Clone for TypesetError

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 TypesetError

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

Formats the value using the given formatter.

impl Display for TypesetError

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

Formats the value using the given formatter.

impl Eq for TypesetError

impl Error for TypesetError

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 TypesetError

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

Equality operator ==.

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

Inequality operator !=.
