Struct ParseNumberError 

pub struct ParseNumberError {
    pub message: String,
    pub line: usize,
    pub column: usize,
}

Rich parse-error diagnostic carrying the offending message together with the 1-based line and column where the parser stopped.

This is a standalone error type (not a variant of OxiNumError) so that the existing OxiNumError size envelope is preserved. Convert via OxiNumError::from(parse_err) (or ?) to fold a positional diagnostic back into the unified error type — the resulting OxiNumError::Parse message will include the line and column.

Examples

use oxinum_core::{OxiNumError, ParseNumberError};

let pe = ParseNumberError::new("unexpected character", 2, 5);
assert!(pe.to_string().contains("line 2"));
assert!(pe.to_string().contains("column 5"));

// Fold into the unified error type.
let e: OxiNumError = pe.into();
assert!(matches!(e, OxiNumError::Parse(_)));
assert!(e.to_string().contains("line 2"));
assert!(e.to_string().contains("col 5"));

Fields

message: String

Human-readable description of why the parse failed.

line: usize

1-based line where the parser stopped.

column: usize

1-based column where the parser stopped.

Implementations

impl ParseNumberError

pub fn new(message: impl Into<String>, line: usize, column: usize) -> Self

Construct a new ParseNumberError from a message and a 1-based (line, column) position.

Trait Implementations

impl Clone for ParseNumberError

fn clone(&self) -> ParseNumberError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseNumberError

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

Formats the value using the given formatter.

impl Display for ParseNumberError

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

Formats the value using the given formatter.

impl Error for ParseNumberError

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 From<ParseNumberError> for OxiNumError

fn from(e: ParseNumberError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseNumberError

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