Variants

StaleHandle

The resource handle refers to a slot that has been freed and reused.

Fields

handle: ResourceId

The stale handle.

NotOwner

The caller is not the owner of the resource.

Fields

handle: ResourceId

The resource handle.

expected_owner: String

The expected owner.

actual_caller: String

The actual caller.

NotAllocated

The resource is not currently allocated (still in pool).

Fields

handle: ResourceId

The resource handle.

BorrowsOutstanding

Outstanding borrows prevent the requested operation.

Fields

handle: ResourceId

The resource handle.

borrow_count: u32

Number of outstanding borrows.

MutableLeaseActive

A mutable lease is active, preventing the requested operation.

Fields

handle: ResourceId

The resource handle.

ReadOnlyLeasesActive

Read-only leases are active, preventing the requested operation.

Fields

handle: ResourceId

The resource handle.

BudgetExceeded

The component’s memory budget would be exceeded.

Fields

component: ComponentId

The component exceeding its budget.

current_bytes: u64

Current memory usage in bytes.

requested_bytes: u64

Requested additional bytes.

budget_bytes: u64

Total budget in bytes.

AllocationFailed

Buffer pool is exhausted and system allocator fallback failed.

Fields

requested_capacity: u32

The requested buffer capacity.

reason: String

The reason for failure.

CapacityExceeded

The write would exceed the buffer’s capacity.

Fields

handle: ResourceId

The resource handle.

capacity: u32

The buffer capacity.

attempted_size: u64

The attempted write size.

OutOfBounds

The offset is out of bounds.

Fields

handle: ResourceId

The resource handle.

offset: u64

The invalid offset.

buffer_size: u64

The buffer size.

Trait Implementations

impl Clone for ResourceError

fn clone(&self) -> ResourceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceError

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

Formats the value using the given formatter.

impl Display for ResourceError

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

Formats the value using the given formatter.

impl Error for ResourceError

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 From<ResourceError> for TorvynError

fn from(e: ResourceError) -> Self

Converts to this type from the input type.

impl PartialEq for ResourceError

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

impl Eq for ResourceError

impl StructuralPartialEq for ResourceError
