Enum PathInvariantError

#[non_exhaustive]
pub enum PathInvariantError {
    EmptyNodes {},
    UnevenIndicesCount {},
    TooManyRelationships {},
    TooManyNodes {},
    EvenIndexOutOfRange {
        index: usize,

}

Represents an error that occurred because a Path’s invariants were violated.

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.

EmptyNodes

Path::nodes must not be empty.

UnevenIndicesCount

Path::indices must have an even number of elements.

TooManyRelationships

Path::relationships must be <= [isize::MAX] - 1.

TooManyNodes

Path::nodes must be <= isize::MAX.

EvenIndexOutOfRange

Path::nodes must be <= isize::MAX.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

index: usize

value: isize

relationships_len: usize

OddIndexOutOfRange

Path::nodes must be <= isize::MAX.

Fields

Trait Implementations

impl Clone for PathInvariantError

fn clone(&self) -> PathInvariantError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathInvariantError

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

Formats the value using the given formatter.

impl Display for PathInvariantError

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

Formats the value using the given formatter.

impl Error for PathInvariantError

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 PathInvariantError

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