Enum read_tree::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 Error for ValidationError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error ocurred.
