Enum StaticExecutionError 

pub enum StaticExecutionError {
    WrongRealm(ExecutionRealm),
    NotFirmwareSubset(McuPlanError),
    ArenaTooSmall,
    FanInTooWide(StepId),
    NonDenseBuffers,
    MissingBuffer(StepId),
    MissingInvocation(StepId),
    OutputArity(StepId),
    KernelFault(StepId),
}

A structured fault raised by the statically linked MCU executor. Every variant is a bounded-arena or contract violation; the executor never allocates and never panics on well-formed firmware plans.

Variants

WrongRealm(ExecutionRealm)

The plan was authorized for a different realm than McuAot.

NotFirmwareSubset(McuPlanError)

The plan is not a valid firmware subset (stateful, hierarchical, …).

ArenaTooSmall

A caller-owned arena was smaller than the plan’s exact requirement.

FanInTooWide(StepId)

A step declares more physical inputs than MAX_STATIC_STEP_INPUTS.

NonDenseBuffers

Buffer identities are not the dense 0..value_slots the executor indexes.

MissingBuffer(StepId)

A step read a buffer that no prior step in topological order produced.

MissingInvocation(StepId)

A step read an invocation input the caller did not supply.

OutputArity(StepId)

The kernel wrote a different output count than the step declares.

KernelFault(StepId)

The bound kernel reported a fault for this step.

impl Eq for StaticExecutionError

impl Error for StaticExecutionError

Available on crate feature std only.

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 StaticExecutionError

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

Equality operator ==.

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

Inequality operator !=.
