Struct CslParseError 

pub struct CslParseError {
    kind: CslParseErrorKind,
    offset: usize,
}

A recoverable CSL parse error: a CslParseErrorKind plus the byte offset into the original input where the problem was detected.

The offset is a byte index (the same convention mos-core SourceSpans use). Use line_col for a 1-based line/column pair, or to_diagnostic to bridge into the compiler diagnostics pipeline.

Examples

use mos_csl::{CslParseErrorKind, parse_style};

let err = parse_style("<not-a-style/>").unwrap_err();
assert!(matches!(err.kind(), CslParseErrorKind::UnexpectedRoot(_)));

Fields

kind: CslParseErrorKind

offset: usize

Implementations

impl CslParseError

pub(crate) const fn new(kind: CslParseErrorKind, offset: usize) -> Self

pub const fn kind(&self) -> &CslParseErrorKind

The kind of parse failure.

pub const fn offset(&self) -> usize

The byte offset into the parsed input where the error was detected.

pub fn line_col(&self, src: &str) -> (usize, usize)

The 1-based (line, column) of this error within src.

src must be the input passed to parse_style; columns count Unicode scalar values.

pub fn to_diagnostic(&self, file: impl Into<PathBuf>) -> Diagnostic

Convert this error into a mos-core [Diagnostic] anchored in file, carrying the MOS0044 code and a zero-width span at offset.

Trait Implementations

impl Clone for CslParseError

fn clone(&self) -> CslParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CslParseError

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

Formats the value using the given formatter.

impl Display for CslParseError

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

Formats the value using the given formatter.

impl Error for CslParseError

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<CslParseError> for CoreError

fn from(err: CslParseError) -> Self

Converts to this type from the input type.

impl PartialEq for CslParseError

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