Struct ParseErrorAt 

pub struct ParseErrorAt {
    pub line: usize,
    pub col: usize,
    pub span_len: usize,
    pub snippet: String,
    pub message: String,
}

A structured parse error with source location and visual context.

Designed to be shown directly to end users (e.g. REST API consumers). Example output:

parse error at 1:5 — expected an operator (==, !=, =in=, ...)
  name=bad=value
      ^

Fields

line: usize

1-based line number.

col: usize

1-based column number (byte-based; accurate for ASCII input).

span_len: usize

Number of characters to underline with ‘^’. At least 1.

snippet: String

The full source line containing the error.

message: String

Human-readable description of what went wrong.

Trait Implementations

impl Clone for ParseErrorAt

fn clone(&self) -> ParseErrorAt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseErrorAt

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

Formats the value using the given formatter.

impl Display for ParseErrorAt

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

Formats the value using the given formatter.

impl PartialEq for ParseErrorAt

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