Variants

UnexpectedEnd

UnexpectedToken(Token<'input>)

Unexpected token.

Lexer(Error)

An error occurred in the lexer.

MoreInput(Vec<Token<'input>>)

Trait Implementations

impl<'input> Debug for Error<'input>

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

Formats the value using the given formatter.

impl<'input> Display for Error<'input>

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

Formats the value using the given formatter.

impl<'input> From<Error<'input>> for String

impl for backwards compatibility.

fn from(value: Error<'input>) -> Self

Converts to this type from the input type.

impl<'input> From<Error> for Error<'input>

fn from(value: Error) -> Self

Converts to this type from the input type.

impl<'input> Ord for Error<'input>

fn cmp(&self, other: &Error<'input>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'input> PartialEq for Error<'input>

fn eq(&self, other: &Error<'input>) -> 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.

impl<'input> PartialOrd for Error<'input>

fn partial_cmp(&self, other: &Error<'input>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
