Struct ParseError 

pub struct ParseError {
    pub kind: ParseErrorKind,
    pub location: Option<OffsetSpan>,
    pub context: Vec<ContextFrame>,
    /* private fields */
}

Structured failure returned by core parsing and structural accessors.

Fields

kind: ParseErrorKind

Machine-inspectable error category.

location: Option<OffsetSpan>

Optional byte location.

context: Vec<ContextFrame>

Context ordered from the innermost operation outward.

Implementations

impl ParseError

pub fn new(kind: ParseErrorKind, message: impl Into<String>) -> Self

Construct a parser error with a typed category and human context.

pub fn format(message: impl Into<String>) -> Self

Construct an invalid-format error.

pub fn bounds(offset: u64, needed: u64, available: u64) -> Self

Construct an out-of-bounds error with the attempted range.

pub fn address(message: impl Into<String>) -> Self

Construct an invalid-address error.

pub fn command(message: impl Into<String>) -> Self

Construct an invalid-load-command error.

pub fn limit(message: impl Into<String>) -> Self

Construct a limit-exhaustion error.

pub fn unsupported(message: impl Into<String>) -> Self

Construct an unsupported-input error.

pub fn validation(message: impl Into<String>) -> Self

Construct a strict-validation error.

pub fn with_location(self, location: OffsetSpan) -> Self

Attach a byte location.

pub fn with_context(self, frame: ContextFrame) -> Self

Add an outer context frame without flattening the original error.

pub fn message(&self) -> &str

Human-readable detail without the category prefix.

pub const fn code(&self) -> &'static str

Stable lowercase dotted diagnostic code for this category.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> Self

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 PartialEq for ParseError

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

Equality operator ==.

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

Inequality operator !=.
