Enum AromaticityError 

pub enum AromaticityError {
    KekulizationFailed {
        reason: String,
    },
    InternalInvariantViolation {
        reason: String,
    },
}

Error from the RDKit-parity experimental aromaticity API.

Unlike assign_aromaticity_ex/ apply_aromaticity_ex (infallible, and unchanged by this addition), this engine requires an explicit kekulization step it does not control the success of, so its entry points return Result rather than silently falling back to another algorithm or panicking.

Variants

KekulizationFailed

The input could not be reduced to a Kekulé form (no BondOrder::Aromatic bonds), which this engine requires as a precondition – mirrors RDKit’s own pipeline, where Kekulize always runs before setAromaticity.

Fields

reason: String

Human-readable detail from the underlying chematic_core::KekuleError.

InternalInvariantViolation

A post-computation sanity check failed (e.g. an aromatic bond with a non-aromatic endpoint atom) – should never happen for chemically valid input; surfaced as an error rather than a panic or a silently wrong result.

Fields

reason: String

Human-readable detail of which invariant failed.

impl Eq for AromaticityError

impl Error for AromaticityError

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
