Enum UnsupportedReason 

#[non_exhaustive]
pub enum UnsupportedReason {
    MissingCapability {
        capability: CoreCapabilityKind,
    },
    Operation {
        operation: &'static str,
    },
    StorageClass {
        storage_class: StorageClass,
    },
}

Deterministic reason why a provider cannot prepare an operation.

Examples

use tenferro_runtime::{CoreCapabilityKind, UnsupportedReason};

let reason = UnsupportedReason::MissingCapability {
    capability: CoreCapabilityKind::Elementwise,
};
assert!(reason.to_string().contains("Elementwise"));

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingCapability

The runtime snapshot has no provider for this core capability.

Fields

capability: CoreCapabilityKind

Missing core capability kind.

Operation

The named operation is unsupported by the selected provider.

Fields

operation: &'static str

Stable operation diagnostic.

StorageClass

The selected provider does not support the required storage class.

Fields

storage_class: StorageClass

Unsupported storage class.

Trait Implementations

impl Clone for UnsupportedReason

fn clone(&self) -> UnsupportedReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnsupportedReason

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

Formats the value using the given formatter.

impl Display for UnsupportedReason

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

Formats the value using the given formatter.

impl Hash for UnsupportedReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UnsupportedReason

fn eq(&self, other: &UnsupportedReason) -> 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.
