Enum Error 

pub enum Error {
    InvalidIdentifier {
        attempted: String,
        reason: &'static str,
    },
    EmptyRegexPattern,
    InvalidRegexFlag {
        flag: char,
    },
    UnbalancedTemplate {
        quasis: usize,
        expressions: usize,
    },
}

All errors that arise when constructing AST nodes from raw input.

Variants

InvalidIdentifier

An identifier was empty or contained an illegal character.

Fields

attempted: String

The string that was attempted.

reason: &'static str

Short description of why it is invalid.

EmptyRegexPattern

A regex literal pattern was empty.

InvalidRegexFlag

A regex literal carried a flag character not recognised by ECMA-262.

Fields

flag: char

The offending flag character.

UnbalancedTemplate

A template literal had a different number of quasis than expressions allow (must satisfy quasis.len() == expressions.len() + 1).

Fields

quasis: usize

Number of literal chunks supplied.

expressions: usize

Number of interpolated expressions supplied.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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 Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
