Errors surfaced by the tenant registry.

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.

RegistryFull

The registry ran out of tenant ids. Unregister unused tenants or raise the range per tenant.

Fields

issued: u32

Number of tenants already issued when exhaustion hit.

OpcodeOutOfRange

Tried to publish an opcode outside the tenant’s reserved range. Almost always a caller bug.

Fields

tenant_id: u32

Tenant id that tripped.

local_opcode: u32

Local opcode the caller supplied.

cap: u32

Cap on the tenant’s local opcode range.

Revoked

Tenant was unregistered concurrently; its handle is stale.

Fields

tenant_id: u32

Tenant id that was revoked.

QuiesceTimeout

Quiesce timed out with inflight slots still outstanding.

Fields

tenant_id: u32

Tenant id whose quiesce tripped.

outstanding: u64

Number of slots still inflight at timeout.

Backpressure

Tenant has reached its configured outstanding-slot cap.

Fields

tenant_id: u32

Tenant id whose backlog is full.

outstanding: u64

Current host-visible outstanding slots.

cap: u64

Configured outstanding-slot cap.

StagingBackpressure

Tenant has reached its configured staging-byte cap.

Fields

tenant_id: u32

Tenant id whose staging byte budget is full.

requested: u64

New bytes requested.

used: u64

Current reserved staging bytes.

cap: u64

Configured staging byte cap.

ResidentHandleBackpressure

Tenant has reached its configured resident-handle cap.

Fields

tenant_id: u32

Tenant id whose resident handle budget is full.

requested: u64

New handles requested.

used: u64

Current reserved resident handles.

cap: u64

Configured resident handle cap.

ResourceUnderflow

Tenant resource accounting would underflow.

Fields

tenant_id: u32

Tenant id whose counter would underflow.

resource: &'static str

Resource counter being released.

requested: u64

Release count requested.

used: u64

Current reserved count.

Pipeline(PipelineError)

Protocol error bubbled up from Megakernel::publish_slot.

Trait Implementations

impl Debug for TenantError

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

Formats the value using the given formatter.

impl Display for TenantError

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

Formats the value using the given formatter.

impl Error for TenantError

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<PipelineError> for TenantError

fn from(source: PipelineError) -> Self

Converts to this type from the input type.
