Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub line: u32,
    pub column: u32,
    pub source_snippet: Option<SourceSnippet>,
}

Fields

message: String

line: u32

column: u32

source_snippet: Option<SourceSnippet>

§Fase 28.d — Optional rustc-style source-context block. None preserves the legacy single-line shape; populated by Parser::with_source callers (and by parse_with_recovery / parse when a source has been attached to the parser). Existing struct-literal call sites use the ..Default::default() idiom (default = None) to stay terse.

Implementations

impl ParseError

pub fn attach_source(self, source: &str, filename: &str) -> ParseError

§Fase 28.d — Attach a SourceSnippet derived from raw source text and filename. Returns self so the call can be chained at the construction site. No-op when line == 0. Idempotent.

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<(), Error>

Formats the value using the given formatter.

impl Default for ParseError

fn default() -> ParseError

Returns the “default value” for a type.

impl Display for ParseError

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

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.
