The single crate-level error for lexing and parsing.

Variants

UnterminatedString

A quoted string runs to end of input without a closing quote.

Fields

line: usize

Line the string started on (1-based).

UnterminatedComment

A /* */ comment runs to end of input without */.

Fields

line: usize

Line the comment started on (1-based).

InvalidNumber

A numeric literal is not a valid number (includes hex literals with bad digits and malformed floats).

Fields

text: String

The offending text.

line: usize

Line the literal starts on (1-based).

InvalidAddress

A number that must be a 32-bit ECU address is negative or exceeds u32::MAX.

Fields

value: f64

The offending value.

line: usize

Line the literal starts on (1-based).

UnexpectedEof

Input ended where a token was required.

Fields

context: &'static str

What the parser was looking for.

UnexpectedToken

A token of a different kind appeared where one was required.

Fields

expected: &'static str

What the parser required (human-readable).

got: String

What was found.

line: usize

Line of the offending token (1-based).

InvalidDatatype

A DATATYPE keyword outside the ASAP2 data-type set.

Fields

text: String

The offending keyword.

line: usize

Line (1-based).

InvalidCharType

A CHARACTERISTIC type keyword outside the ASAP2 set (VALUE, CURVE, MAP, VAL_BLK, ASCII).

Fields

text: String

The offending keyword.

line: usize

Line (1-based).

InvalidConversionType

A COMPU_METHOD conversion type outside the supported set (RAT_FUNC, LINEAR, TABLE, IDENTITY/IDENTICAL).

Fields

text: String

The offending keyword.

line: usize

Line (1-based).

UnterminatedBlock

A /begin NAME block ran to end of input without its /end NAME.

Fields

block: String

The block keyword.

line: usize

Line the /begin appeared on (1-based).

BlockMismatch

A /end NAME closed a different block than the innermost open one.

Fields

opened: String

The innermost open block keyword.

closed: String

The /end keyword.

line: usize

Line of the /end (1-based).

MissingProject

No /begin PROJECT block was found at the top level.

DepthLimitExceeded

/begin blocks nested deeper than the parser’s limit (MAX_DEPTH) — a guard against pathological input, never triggered by conforming files.

Fields

line: usize

Line of the offending /begin (1-based).

Implementations

impl A2lError

pub fn line(&self) -> Option<usize>

The 1-based line the error was detected on, when applicable.

Trait Implementations

impl Clone for A2lError

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 A2lError

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

Formats the value using the given formatter.

impl Display for A2lError

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

Formats the value using the given formatter.

impl Error for A2lError

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 A2lError

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

Equality operator ==.

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

Inequality operator !=.
