Enum TopologyError 

pub enum TopologyError {
    Authority(LeaseError),
    Catalog(CatalogManifestError),
    Invalid(String),
    Conflict(String),
    Fenced,
    Protocol(String),
    Contended,
    ReadTimedOut,
    Unsupported(String),
    PlanningBusy,
    PlanningTimedOut,
}

Typed, stable control-path failures. No error authorizes a topology or state fallback.

Variants

Authority(LeaseError)

Shared authority I/O or validation failed.

Catalog(CatalogManifestError)

Catalog content failed validation.

Invalid(String)

Malformed proposal, durable state or exhausted identity domain.

Conflict(String)

Expected parent/reference/deployment does not match durable authority.

Fenced

Supplied leader proof is stale.

Protocol(String)

A required protocol/storage capability is not available.

Contended

The bounded CAS/deadline budget was exhausted; authoritative status must be reread.

ReadTimedOut

A status read exceeded its control-path deadline.

Unsupported(String)

A candidate requires an unsupported semantic transformation or execution contract.

PlanningBusy

Another bounded local candidate compilation owns this process’s planning slot.

PlanningTimedOut

Local validation exceeded its bounded control-path budget without admitting an operation.

Implementations

impl TopologyError

pub const fn code(&self) -> &'static str

Stable registry code for this typed failure.

Trait Implementations

impl Debug for TopologyError

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

Formats the value using the given formatter.

impl Display for TopologyError

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

Formats the value using the given formatter.

impl Error for TopologyError

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<CatalogManifestError> for TopologyError

fn from(error: CatalogManifestError) -> Self

Converts to this type from the input type.

impl From<LeaseError> for TopologyError

fn from(source: LeaseError) -> Self

Converts to this type from the input type.
