Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AtomIndexOutOfRange

原子下标越界

Fields

index: u32

越界的下标

num_atoms: u32

实际原子数

SelfLoop

试图添加自环。分子图中不存在自环。

Fields

atom: u32

两端相同的那个原子

MolIndexOutOfRange

分子下标越界

Fields

index: u32

越界的下标

num_mols: u32

实际分子数

BondIndexOutOfRange

键下标越界

Fields

index: u32

越界的下标

num_bonds: u32

实际键数

BatchTooLarge

批规模超出 u32 索引上限

Fields

what: &'static str

溢出的是哪一类实体(“atoms” / “bonds” / “molecules”)

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for Error
