Enum DerivationError 

pub enum DerivationError {
    InvalidPolicy {
        source: RunPolicyError,
    },
    ArithmeticOverflow {
        policy: String,
        operation: String,

}

Error returned when run derivation fails.

Variants

InvalidPolicy

The run policy payload is invalid for derivation.

Fields

source: RunPolicyError

The typed policy validation failure.

ArithmeticOverflow

Arithmetic overflow would occur during run derivation. This indicates the derivation request cannot be fulfilled with representable values.

Fields

policy: String

The run policy that caused the overflow.

operation: String

Description of the overflowed calculation.

InvalidTaskIdForRunConstruction

Run construction failed because the task identifier is nil/invalid.

Fields

task_id: TaskId

Rejected task identifier.

RunConstructionFailed

Run construction failed for a reason other than task identifier shape.

Fields

task_id: TaskId

Task identifier associated with the failed construction.

source: RunInstanceConstructionError

Typed construction failure returned by core run constructors.

Trait Implementations

impl Clone for DerivationError

fn clone(&self) -> DerivationError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DerivationError

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

Formats the value using the given formatter.

impl Display for DerivationError

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

Formats the value using the given formatter.

impl Error for DerivationError

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 DerivationError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
