reason: &'static str

RangeAuthorityViolation

The stable key namespace and memory ID range do not match.

Fields

stable_key: String

Stable key being registered.

id: u8

Trait Implementations

impl Debug for MemoryRegistryError

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

Formats the value using the given formatter.

impl Display for MemoryRegistryError

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

impl Error for MemoryRegistryError

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.
