    pub level: IssueLevel,
    pub message: String,
    pub span: &'a str,
    pub line: usize,
    pub column: usize,
}

Tokenization issue for error reporting

Represents a problem encountered during tokenization with location information and severity level for appropriate handling.

Fields

level: IssueLevel

Issue severity level

message: String

Human-readable error message

span: &'a str

Source span where issue occurred

line: usize

Line number where issue occurred (1-based)

column: usize

Column number where issue occurred (1-based)

Implementations

impl<'a> TokenIssue<'a>

pub const fn new( level: IssueLevel, message: String, span: &'a str, line: usize, column: usize, ) -> Self

Create new tokenization issue

Arguments

• level - Severity level of the issue
• message - Human-readable description
• span - Source text span where issue occurred
• line - Line number (1-based)
• column - Column number (1-based)

pub const fn warning( message: String, span: &'a str, line: usize, column: usize, ) -> Self

Create warning issue

pub const fn error( message: String, span: &'a str, line: usize, column: usize, ) -> Self

Create error issue

pub const fn critical( message: String, span: &'a str, line: usize, column: usize, ) -> Self

Create critical issue

pub const fn is_error(&self) -> bool

Check if this is an error-level issue

pub fn location_string(&self) -> String

Get formatted location string

pub fn format_issue(&self) -> String

Get formatted issue string for display

Trait Implementations

impl<'a> Clone for TokenIssue<'a>

fn clone(&self) -> TokenIssue<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TokenIssue<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for TokenIssue<'a>

fn eq(&self, other: &TokenIssue<'a>) -> 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.
