Struct TokenError 

pub struct TokenError {
    pub token: char,
    pub line: usize,
    pub col: usize,
}

An error during tokenization

Fields

token: char

The invalid token

line: usize

The line that is invalid

col: usize

The column in that line that’s invalid

Implementations

impl TokenError

pub fn new(token: char, line: usize, col: usize) -> Self

Creates a new token error with context

Trait Implementations

impl Clone for TokenError

fn clone(&self) -> TokenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TokenError

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TokenError

impl Error for TokenError

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 TokenError

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