Struct ParseError 

pub struct ParseError {
    pub message: String,
    pub range: TextRange,
    pub found: Option<String>,
    pub expected: Vec<String>,
}

An error encountered during parsing.

Fields

message: String

A description of the error.

range: TextRange

The source range where the error occurred.

For “expected X” errors, this covers the found token so that diagnostic carets underline it. For recovery errors, this spans the tokens wrapped in the ERROR node.

found: Option<String>

The token that was found (for “expected X, found Y” errors).

expected: Vec<String>

The list of expected tokens (for structured error messages).

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

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.
