A typed refusal or failure from crate::runtime::ComponentRuntime or crate::runtime::mailbox_integer.

Variants

ZeroSchedulerThreads

The policy asked for zero scheduler threads. beamr would silently substitute the machine’s parallelism; the wrapper refuses instead — policy values are stated, never defaulted.

ZeroOperationTimeout

The policy asked for a zero operation timeout, which would make every spawn, mailbox round-trip, and tombstone observation time out immediately.

Composition

Scheduler composition (BIF population + construction) failed.

Fields

source: SchedulerCompositionError

Exact typed composition refusal.

SupportModuleLoad

The runtime refused or failed to hot-load a support module.

Fields

detail: String

Exact loader refusal.

SupportModuleAbsent

A support module vanished from the committed table immediately after its hot load reported success.

Fields

module: String

Module whose committed entry was missing.

SupportModuleDeferredBifImports

A freshly loaded support module’s committed import table still defers erlang:* entries — process-fatal at first dispatch, refused up front (the same wall the registry applies to component bytecode).

Fields

module: String

Refused module.

imports: String

The deferred erlang:name/arity entries.

SupportModulePurge

A retained old generation of a support module could not be safely purged during unload.

Fields

module: String

Module whose old generation resisted the purge.

detail: String

Exact beamr purge refusal.

SupportModuleDelete

Deleting a support module’s current generation failed — the module was not loaded (a stale handle) or still had unpurged old code.

Fields

module: String

Module the delete step refused.

SupportModuleStillLoaded

A support module was still committed after its verified unload — the runtime never reports an unload it cannot prove.

Fields

module: String

Module still present after purge + delete.

ProcessResidue

Final teardown was refused because the process tree still has residue; every component must complete its ordered stop first.

Fields

count: usize

Processes still alive on the scheduler.

MailboxReservedRangeInvalid

The reserved bound handed to crate::runtime::mailbox_integer lies outside the mailbox integer domain, leaving no valid value to fold into.

Fields

reserved_below: i64

The refused bound (every integer strictly below it is reserved).

max: i64

The largest representable mailbox integer.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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.
