Struct ValenceError 

pub struct ValenceError {
    pub atom: AtomIdx,
    pub actual: u8,
    pub allowed: &'static [u8],
}

A valence violation on a specific atom.

Returned by validate_valence for each atom whose observed bond-order sum exceeds all allowed normal valences (after formal-charge adjustment).

Fields

atom: AtomIdx

Index of the over-valenced atom.

actual: u8

Observed bond-order sum (+ explicit bracket H count).

allowed: &'static [u8]

Allowed normal valences for the element (from crate::Element::normal_valences).

Trait Implementations

impl Clone for ValenceError

fn clone(&self) -> ValenceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValenceError

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

Formats the value using the given formatter.

impl Display for ValenceError

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

Formats the value using the given formatter.

impl Error for ValenceError

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>)
