Enum SnapshotReadRequestError 

pub enum SnapshotReadRequestError {
    ObservationLimitTooLarge,
    UnsupportedMethod,
    Plan(OperationPlanError),
    Payload(IcRequestError),
}

Typed exact original-plan/read-payload admission failure.

Variants

ObservationLimitTooLarge

The descriptive ceiling exceeds its maintained bound.

UnsupportedMethod

Only the implemented snapshot-list codec is admitted.

Plan(OperationPlanError)

Original operation plan rejects binding derivation.

Payload(IcRequestError)

Exact read target or separate observation digest differs.

Trait Implementations

impl Debug for SnapshotReadRequestError

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

Formats the value using the given formatter.

impl Display for SnapshotReadRequestError

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

Formats the value using the given formatter.

impl Error for SnapshotReadRequestError

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.
