Struct Capabilities 

#[non_exhaustive]
pub struct Capabilities {
    pub compiled: Vec<BackendKind>,
    pub available: Vec<BackendKind>,
}

Compile-time + runtime snapshot of hardware backend capabilities.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

compiled: Vec<BackendKind>

Backends that were compiled in (selected via Cargo features).

available: Vec<BackendKind>

Backends that compiled in AND are usable at runtime (e.g. a cuda feature compiled but no CUDA driver → not in this list). Same as compiled for now; populated by crate::device::detect in a later phase.

Implementations

impl Capabilities

pub fn new(compiled: Vec<BackendKind>) -> Self

Build a snapshot from the list of compiled-in backends.

available is initialised as a clone of compiled; real runtime filtering lands once voxora-backend gains a candle feature in 0.2.x.

pub fn is_compiled(&self, kind: BackendKind) -> bool

True iff kind is compiled in.

pub fn is_available(&self, kind: BackendKind) -> bool

True iff kind is compiled in AND usable at runtime.

pub fn iter_compiled(&self) -> Iter<'_, BackendKind>

Iterate over backends that were compiled in.

pub fn iter_available(&self) -> Iter<'_, BackendKind>

Iterate over backends that compiled in AND are usable at runtime.
