Enum ExternError

pub enum ExternError {
    Syntax(Box<SyntaxError<ExternSignature>>),
    Lex(Box<Error<LexErrorKind>>),
    InvalidPragmaArguments,
    NoSignature,
    NoName,
    PragmaIsNotExtern,
    NoReturnOrParameters,
    Name(Box<IdentifierValidationError>),
}

An error that can occur when parsing an extern signature.

Variants

Syntax(Box<SyntaxError<ExternSignature>>)

An error occurred while parsing the contents of the extern signature.

Lex(Box<Error<LexErrorKind>>)

An error occurred while lexing the extern signature.

InvalidPragmaArguments

Pragma arguments are invalid.

NoSignature

No signature found.

NoName

No extern name found.

PragmaIsNotExtern

Pragma is not EXTERN.

NoReturnOrParameters

The extern definition has a signature but it has neither a return nor parameters.

Name(Box<IdentifierValidationError>)

Either the name of the extern or one of its parameters is invalid.

Trait Implementations

impl Clone for ExternError

fn clone(&self) -> ExternError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExternError

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

Formats the value using the given formatter.

impl Display for ExternError

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

Formats the value using the given formatter.

impl Error for ExternError

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<Box<IdentifierValidationError>> for ExternError

fn from(source: Box<IdentifierValidationError>) -> Self

Converts to this type from the input type.

impl From<ExternError> for CallResolutionError

fn from(source: ExternError) -> Self

Converts to this type from the input type.

impl PartialEq for ExternError

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