Enum RRefError 

pub enum RRefError {
    RegionNotFound(RegionId),
    AllocationInvalid,
    RegionMismatch {
        expected: RegionId,
        actual: RegionId,
    },
    RegionClosed,
    WrongRegion,
}

Error returned when accessing an RRef fails.

Variants

RegionNotFound(RegionId)

The region does not exist in the runtime state.

AllocationInvalid

The heap allocation is no longer valid (deallocated or type mismatch).

RegionMismatch

The region ID in the RRef doesn’t match the provided region.

Fields

expected: RegionId

The region ID stored in the RRef.

actual: RegionId

The region ID that was provided.

RegionClosed

The region is closed and its heap has been reclaimed.

WrongRegion

The access witness references a different region than expected.

Trait Implementations

impl Clone for RRefError

fn clone(&self) -> RRefError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RRefError

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

Formats the value using the given formatter.

impl Display for RRefError

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

Formats the value using the given formatter.

impl Error for RRefError

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 RRefError

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