Errors that can occur while assembling instructions.

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.

#[non_exhaustive]

DuplicateLabel

A label was declared multiple times.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

label: String

The name of the conflicting label.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

DuplicateMacro

A macro was declared multiple times.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: String

The name of the conflicting macro.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

ExpressionTooLarge

A push instruction was too small for the result of the expression.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

expr: Expression

The oversized expression.

value: BigInt

The evaluated value of the expression.

spec: Op<()>

The specifier.

backtrace: Backtrace

The location of the error.

ExpressionNegative

An expression evaluated to a negative number.

Fields

expr: Expression

The oversized expression.

value: BigInt

The evaluated value of the expression.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

UnsizedPushTooLarge

The value provided to an unsized push (%push) was too large.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

UndeclaredLabels

A label was used without being defined.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

labels: Vec<String>

The labels that were used without being defined.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

UndeclaredInstructionMacro

An instruction macro was used without being defined.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: String

The macro that was used without being defined.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

UndeclaredExpressionMacro

An expression macro was used without being defined.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

name: String

The macro that was used without being defined.

backtrace: Backtrace

The location of the error.

#[non_exhaustive]

ParseInclude

An import or include failed to parse.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: ParseError

The next source of this error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

where Self: Debug + Display,

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 ErrorCompat for Error

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.

impl From<Error> for Error

fn from(error: AssembleError) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(error: ParseError) -> Self

Converts to this type from the input type.
