MemoryManagerLayoutError

Invalid or unsupported persisted manager metadata. No writes are performed when reporting these failures. Memory implementations must obey 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.

UnsupportedByteOrder

This adapter supports the little-endian IC/current native layout only.

ZeroBucketSize

The persisted bucket size is zero.

ReservedHeader

Reserved header fields are not recognized by this adapter.

BucketCount

The allocated count exceeds the finite bucket table.

Fields

count: u16

BucketTable

Allocated buckets must be a dense prefix and all later entries unused.

Fields

index: u16

VirtualExtent

Virtual extent disagrees with the number of assigned buckets.

Fields

id: u8

TruncatedBacking

Backing memory does not cover every assigned bucket.

Fields

physical_pages: u64

required_pages: u64

ExtentOverflow

Backing size cannot be represented in bytes.

RuntimeMismatch

A live manager’s cached state differs from persisted metadata.

impl Eq for MemoryManagerLayoutError

impl Error for MemoryManagerLayoutError

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
