Enum BondOrder 

pub enum BondOrder {
    Single,
    Double,
    Triple,
    Quadruple,
    Aromatic,
    Up,
    Down,
}

Bond order, covering all SMILES bond types.

Variants

Single

Single bond -

Double

Double bond =

Triple

Triple bond #

Quadruple

Quadruple bond $ (used in some metal complexes)

Aromatic

Aromatic bond : (pre-Kekulization representation)

Up

Stereo bond / (E/Z specification)

Down

Stereo bond \ (E/Z specification)

Implementations

impl BondOrder

pub fn order_value(self) -> Option<f32>

Fractional bond order. Returns None for aromatic (non-integer).

pub fn order_int(self) -> u8

Integer bond order used for valence calculations. Aromatic and stereo bonds count as 1.

pub fn smiles_char(self) -> char

The SMILES character that represents this bond order.

Trait Implementations

impl Clone for BondOrder

fn clone(&self) -> BondOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BondOrder

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

Formats the value using the given formatter.

impl Display for BondOrder

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

Formats the value using the given formatter.

impl Hash for BondOrder

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 BondOrder

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