NoAtomToBond

UnexpectedCharacter(char, usize)

Unexpected character in SMILES string.

UnexpectedEndOfInput(String)

Unexpected end of input.

MissingElementInBracketAtom

Bracket Atom must have an element

ChargeWithoutSign

UnclosedParenthesis

Missing closing parenthesis.

UnopenedParenthesis

Missing opening parenthesis.

EmptyBranch

Empty branch.

UnclosedRing(Vec<u8>)

Unclosed ring.

MismatchedRingBond(u8)

Mismatched bond types for ring closure.

BondWithoutPrecedingAtom

Bond without preceding atom.

BondWithoutFollowingAtom

Bond without following atom.

HydrogenWithHydrogenCount

Trait Implementations

impl Clone for ParserError

fn clone(&self) -> ParserError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.

impl From<BondError> for ParserError

fn from(source: BondError) -> Self

Converts to this type from the input type.

impl From<MoleculeError> for ParserError

fn from(source: MoleculeError) -> Self

Converts to this type from the input type.

impl From<NodeError> for ParserError

fn from(source: NodeError) -> Self

Converts to this type from the input type.

impl PartialEq for ParserError

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