Structured validation failures for offload contracts.

Variants

UnsupportedSchemaVersion(u32)

A serialized plan used an unsupported schema version.

EmptyUnitId

A logical identifier was empty or whitespace-only.

ZeroSizedUnit

A unit had no bytes to manage.

Fields

id: OffloadUnitId

The invalid unit identifier.

DuplicateUnitId

More than one unit used the same stable identifier.

Fields

id: OffloadUnitId

The duplicated identifier.

ByteTotalOverflow

Summing unit sizes overflowed the stable byte counter.

Fields

tier: MemoryTier

The tier whose total overflowed.

BudgetExceeded

Explicit assignments exceeded a configured finite budget.

Fields

tier: MemoryTier

The over-budget tier.

planned_bytes: u64

The checked planned total.

budget_bytes: u64

The configured finite budget.

ContradictoryAssignment

A policy and tier assignment had incompatible meanings.

Fields

id: OffloadUnitId

The invalid unit identifier.

policy: ResidencyPolicy

The requested policy.

tier: MemoryTier

The requested tier.

reason: &'static str

A stable explanation of the contradiction.

ZeroPrefetchDepth

Prefetching was configured with a meaningless zero-unit lookahead.

Trait Implementations

impl Clone for OffloadError

fn clone(&self) -> OffloadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OffloadError

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

Formats the value using the given formatter.

impl Display for OffloadError

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

Formats the value using the given formatter.

impl Eq for OffloadError

impl Error for OffloadError

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 OffloadError

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

Equality operator ==.

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

Inequality operator !=.
