Enum ParsingError

pub enum ParsingError<'input> {
    Grammar(Error<Rule>),
    CouldntBuildAST(SimpleError<'input>),
}

Error happened while parsing, this can happen due to a grammar parsing error, or if the syntax it’s right, because the of a series of ASTBuildingError.

Variants

Grammar(Error<Rule>)

Happens if the script doesn’t match Moon Script’s grammar.

CouldntBuildAST(SimpleError<'input>)

Happens if the grammar is right, but at least one ASTBuildingError happens.

Why isn’t this a series of ASTBuildingErrors?: Individual programs are extremely unlikely to manually use them internally, but rather want a clear output telling why the script is wrong, with simple_detailed_error::SimpleError, Moon Script is able to specifies as many errors as possible using a clear tree structure, and errors are given with colors* when printing errors, showing with clarity where the error happens.

• For accessibility, please, read the colored create used by simple_detailed_error, which uses NO_COLOR.

Implementations

impl<'input> ParsingError<'input>

pub fn couldnt_build_ast_error(self) -> Option<SimpleError<'input>>

impl<'input> ParsingError<'input>

pub fn to_simple_error(self) -> SimpleError<'input>

Turns this parsing error into a SimpleError that can easily be displayed to developers for discovering what was wrong when they wrote a Script.

Trait Implementations

impl<'input> Clone for ParsingError<'input>

fn clone(&self) -> ParsingError<'input>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'input> Debug for ParsingError<'input>

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

Formats the value using the given formatter.

impl<'input> Display for ParsingError<'input>

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

Formats the value using the given formatter.

impl<'input> Error for ParsingError<'input>

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<'input> From<ParsingError<'input>> for SimpleError<'input>

fn from(value: ParsingError<'input>) -> Self

Converts to this type from the input type.
