Struct BackendCapabilities 

pub struct BackendCapabilities {
    pub cpu: CpuFeatures,
    pub metal: bool,
    pub cuda: bool,
}

Backend availability for a codec/runtime combination.

Fields

cpu: CpuFeatures

Host CPU feature set.

metal: bool

True when Metal is available to this crate.

cuda: bool

True when CUDA is available to this crate.

Implementations

impl BackendCapabilities

pub fn compile_time_defaults() -> BackendCapabilities

Return default capabilities implied by the current build target.

This does not probe GPU devices or runtime libraries. Codec facades and adapters must further gate the returned device flags by their compiled features and runtime availability.

pub const fn supports(self, request: BackendRequest) -> bool

Return whether a backend request can be satisfied.

pub fn resolve(self, request: BackendRequest) -> Option<BackendKind>

Resolve a backend request to the concrete backend that should run.

Auto resolves to CPU here. Workload-aware device promotion belongs in codec-specific route planners that have benchmark evidence for the requested operation.

pub const fn first_available_accelerator(self) -> Option<BackendKind>

Return an available accelerator backend without implying it should be selected for a workload.

Trait Implementations

impl Clone for BackendCapabilities

fn clone(&self) -> BackendCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BackendCapabilities

impl Debug for BackendCapabilities

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

Formats the value using the given formatter.

impl Eq for BackendCapabilities

impl PartialEq for BackendCapabilities

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