Struct spinoso_regexp::SyntaxError

pub struct SyntaxError(_);

Error that indicates a given Regexp pattern could not be parsed when given as a /.../ literal in Ruby source code.

This error is typically generated at parse-time.

This error corresponds to the Ruby SyntaxError Exception class.

Examples

let err = SyntaxError::new();
assert_eq!(err.message(), "SyntaxError");

let err = SyntaxError::with_message("premature end of char-class");
assert_eq!(err.message(), "premature end of char-class");

Implementations

impl SyntaxError

pub const fn new() -> Self

Construct a new, default syntax error.

Examples

const ERR: SyntaxError = SyntaxError::new();
assert_eq!(ERR.message(), "SyntaxError");

pub const fn with_message(message: &'static str) -> Self

Construct a new syntax error with a message.

Examples

const ERR: SyntaxError = SyntaxError::with_message("premature end of char-class");
assert_eq!(ERR.message(), "premature end of char-class");

pub fn message(&self) -> &str

Retrieve the exception message associated with this syntax error.

Examples

let err = SyntaxError::new();
assert_eq!(err.message(), "SyntaxError");

let err = SyntaxError::with_message("premature end of char-class");
assert_eq!(err.message(), "premature end of char-class");

Trait Implementations

impl Clone for SyntaxError

fn clone(&self) -> SyntaxError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxError

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

Formats the value using the given formatter.

impl Display for SyntaxError

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

Formats the value using the given formatter.

impl Error for SyntaxError

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<&'static str> for SyntaxError

fn from(message: &'static str) -> Self

Converts to this type from the input type.

impl From<String> for SyntaxError

fn from(message: String) -> Self

Converts to this type from the input type.

impl From<SyntaxError> for Error

fn from(err: SyntaxError) -> Self

Converts to this type from the input type.

impl Hash for SyntaxError

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 Ord for SyntaxError

fn cmp(&self, other: &SyntaxError) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SyntaxError> for SyntaxError

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

impl PartialOrd<SyntaxError> for SyntaxError

fn partial_cmp(&self, other: &SyntaxError) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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