Enum Chirality 

pub enum Chirality {
    None,
    CounterClockwise,
    Clockwise,
    SquarePlanar(SquarePlanarPermutation),
}

Chirality as specified in OpenSMILES: tetrahedral (@/@@) or, since this crate also models coordination complexes, square-planar (@SP1/@SP2/@SP3).

Variants

None

No chirality specified.

CounterClockwise

@ — counterclockwise (looking from the first neighbor).

Clockwise

@@ — clockwise.

SquarePlanar(SquarePlanarPermutation)

@SP1/@SP2/@SP3 — square-planar (4-coordinate) stereo.

Implementations

impl Chirality

pub fn is_tetrahedral(&self) -> bool

true only for Self::CounterClockwise/Self::Clockwise — the classic tetrahedral-parity forms every CIP/ECFP/dedup consumer written before square-planar existed assumes. Consumers that mean “is this a real tetrahedral stereocenter” must check this, not != Self::None, now that a second non-tetrahedral kind of “not None” chirality exists.
