Enum SyntaxParseError 

pub enum SyntaxParseError {
    NoTags,
    InvalidOpeningToken,
    InvalidClosingToken,
    UnopenedBrackets,
    UnclosedBrackets,
    InvalidSequence(Token, Token),
}

Possible syntax errors

Variants

NoTags

The boolean tag expression contains no tags (there must be at least 1)

InvalidOpeningToken

The first lexical token of the boolean tag expression is invalid

InvalidClosingToken

The last lexical token of the boolean tag expression is invalid

UnopenedBrackets

There are more closing brakets than opening brackets in the boolean tag expression

UnclosedBrackets

There are more opening brakets than closing brackets in the boolean tag expression

InvalidSequence(Token, Token)

There is an invalid token order/sequence in the boolean tag expression

Trait Implementations

impl Clone for SyntaxParseError

fn clone(&self) -> SyntaxParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxParseError

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

Formats the value using the given formatter.

impl Display for SyntaxParseError

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

Formats the value using the given formatter.

impl Error for SyntaxParseError

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 From<SyntaxParseError> for ParseError

fn from(source: SyntaxParseError) -> Self

Converts to this type from the input type.

impl Hash for SyntaxParseError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SyntaxParseError

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