Struct ParseError 

pub struct ParseError {
    pub line: usize,
    pub col: usize,
    pub code: String,
    pub message: String,
}

An OML source string could not be parsed – raised by crate::oml::read_oml, mirroring Python’s ParseError in ~/dev/omnist/omnist/errors.py. Carries the same “line N, col N: msg” convention the Python reference’s scanner/parser produce.

Fields

line: usize

Line number where parsing failed (1-indexed).

col: usize

Column number where parsing failed (1-indexed).

code: String

The spec’s stable machine-readable code (omnist-spec §8.3.1, e.g. parse.unexpected-token, parse.codec-syntax).

message: String

Human-readable parse failure description.

Implementations

impl ParseError

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

Construct a new ParseError with position coordinates and the spec’s parse.* code.

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

Construct a parse.codec-syntax error (omnist-spec §8.3.1): input a JSON/YAML/TOML/XML codec could not accept, whether malformed in its own format or refused by a byte-level precondition the spec imposes ahead of the codec (E-24).

pub fn position(&self) -> String

The text position path (line:col, omnist-spec §8.4) of this error.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Eq for ParseError

impl Error for ParseError

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<ParseError> for OmnistError

fn from(source: ParseError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseError

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

Equality operator ==.

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

Inequality operator !=.
