Enum yash_arith::TokenError

pub enum TokenError {
    InvalidNumericConstant,
    InvalidCharacter,
}

Cause of a tokenization error

Variants

InvalidNumericConstant

A value token contains an invalid character.

InvalidCharacter

An expression contains a character that is not a whitespace, operator, or number.

Trait Implementations

impl Clone for TokenError

fn clone(&self) -> TokenError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenError

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

Formats the value using the given formatter.

impl Display for TokenError

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

Formats the value using the given formatter.

impl Error for TokenError

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<E1, E2> From<TokenError> for ErrorCause<E1, E2>

fn from(e: TokenError) -> Self

Converts to this type from the input type.

impl From<TokenError> for SyntaxError

fn from(source: TokenError) -> Self

Converts to this type from the input type.

impl Hash for TokenError

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 TokenError

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