Fields

expected: String

found: String

Coded

A JSONata-spec-coded parse error (S0214-S0217 for the %/@ operators). Code is at the start of the message (matching the DateTimeError::Coded convention from the datetime picture-string engine) so test_reference_suite.py’s extract_error_code() finds it.

Fields

code: &'static str

message: String

Implementations

impl ParserError

pub fn display_message(&self) -> String

The full display-ready message: Coded variants (e.g. S0214) are already exactly “code: message” via Display, so they pass through unchanged; every other variant gets a “Parse error: “ prefix added. Used by both the Python bindings (src/lib.rs) and the jsonata CLI.

Trait Implementations

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

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.
