Enum GraphSelectionError 

pub enum GraphSelectionError {
    EmptyProperty,
    ReservedProperty(String),
    FullScanRequiresOptIn,
}

Invalid selection metadata rejected before a query executes.

Variants

EmptyProperty

Property names must not be empty.

ReservedProperty(String)

The name would collide with loader-owned result metadata.

FullScanRequiresOptIn

An all-nodes or all-edges source requires explicit acknowledgement.

Trait Implementations

impl Clone for GraphSelectionError

fn clone(&self) -> GraphSelectionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphSelectionError

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

Formats the value using the given formatter.

impl Display for GraphSelectionError

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

Formats the value using the given formatter.

impl Eq for GraphSelectionError

impl Error for GraphSelectionError

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 From<GraphSelectionError> for GraphLoadError

fn from(source: GraphSelectionError) -> Self

Converts to this type from the input type.

impl PartialEq for GraphSelectionError

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

Equality operator ==.

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

Inequality operator !=.
