Error code range: E0300–E0399.

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

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
