RuntimeConstructionError

Failure to construct a memory runtime without overwriting unrecognized backing memory.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidBucketSize

Zero pages cannot form a bucket.

BucketSizeMismatch

Explicit policy differs from the actual durable setting.

Fields

persisted: u16

requested: u16

Layout(MemoryManagerLayoutError)

Persisted manager metadata failed bounded validation.

ForeignMemory

Nonempty backing memory does not contain a MemoryManager header.

Fields

observed_magic: [u8; 3]

First three bytes found in the nonempty backing memory.

UnsupportedMemoryManagerVersion

Backing memory contains an unsupported MemoryManager layout version.

Fields

observed: u8

Version byte found after the MemoryManager magic.

supported: u8

Version supported by the pinned ic-stable-structures dependency.

impl Eq for RuntimeConstructionError

impl Error for RuntimeConstructionError

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
