Enum ValidationError

pub enum ValidationError {
    Empty,
    MultipleRoots,
    IllegalStructure,
}

An error returned when validating a vertex slice.

Variants

Empty

The vertex slice is empty.

Nodes must always have exactly one root. The buffer therefor needs to have at least one entry.

MultipleRoots

The vertex slice contains more than one root node.

Nodes can only have exactly one root node.

IllegalStructure

Some of the lengths of the vertices do not match up. Ensure a vertex does not have more descendants than its ancestors.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 ValidationError

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