Enum BackendSupportState 

pub enum BackendSupportState {
    Unknown,
    KnownUnsupported,
    DisabledByFeature,
    RuntimeSupported,
}

Runtime implementation state for a known backend token.

BackendKind is intentionally broader than the current runtime. This type keeps operators from mistaking “UDB knows the name” for “this binary can execute it”.

Variants

Unknown

The token does not map to any known backend.

KnownUnsupported

UDB has metadata for this backend, but no runtime implementation yet.

DisabledByFeature

UDB has a runtime implementation, but this binary was built without it.

RuntimeSupported

This binary includes the runtime plugin for the backend.

Implementations

impl BackendSupportState

pub fn as_str(self) -> &'static str

pub fn is_runtime_supported(self) -> bool

pub fn diagnostic(self, backend: &str) -> String

Trait Implementations

impl Clone for BackendSupportState

fn clone(&self) -> BackendSupportState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BackendSupportState

impl Debug for BackendSupportState

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

Formats the value using the given formatter.

impl Eq for BackendSupportState

impl PartialEq for BackendSupportState

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