Implementations

impl Error

pub fn at_node(self, node: Node<'_>, source: &str) -> Self

pub fn expect_syntax_node( source: &str, expected: &str, actual: Node<'_> ) -> Result<()>

pub fn expect_argument_amount( function_name: &str, expected: usize, actual: usize ) -> Result<()>

pub fn is_type_check_error(&self, other: &Error) -> bool

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(value: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<LanguageError> for Error

fn from(value: LanguageError) -> Self

impl PartialEq for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
