Struct ParseError 

#[non_exhaustive]
pub(crate) struct ParseError {
    context: Option<Span>,
    description: Cow<'static, str>,
    expected: Option<&'static [Expected]>,
    unexpected: Option<Span>,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

context: Option<Span>

description: Cow<'static, str>

expected: Option<&'static [Expected]>

unexpected: Option<Span>

Implementations

impl ParseError

pub fn new(description: impl Into<Cow<'static, str>>) -> ParseError

pub fn with_context(self, context: Span) -> ParseError

pub fn with_expected(self, expected: &'static [Expected]) -> ParseError

pub fn with_unexpected(self, unexpected: Span) -> ParseError

pub fn context(&self) -> Option<Span>

pub fn description(&self) -> &str

pub fn expected(&self) -> Option<&'static [Expected]>

pub fn unexpected(&self) -> Option<Span>

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 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.
