Struct ParseError 

pub struct ParseError { /* private fields */ }

A parse error with span and structured error kind

Implementations

impl ParseError

pub fn message(&self) -> String

Get the primary message for this error

pub const fn byte_range(&self) -> Range<usize>

Byte offsets start..end of the primary error location in the source.

pub fn help(&self) -> Option<String>

Short, actionable fix suggestion if one is known.

Intended for editor integrations that want a one-line hint (e.g. an LSP code-action title) without parsing the rendered snippet.

pub fn related(&self) -> Vec<(Range<usize>, String)>

Secondary locations worth pointing at alongside the primary span, as (byte_range, label) pairs (e.g. the unmatched opening delimiter).

pub const fn code(&self) -> Option<&str>

Get error code if available

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

Formats the value using the given formatter.

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 PartialEq for ParseError

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