Struct BackendEntry 

pub struct BackendEntry {
    pub kind: BackendKind,
    pub available: bool,
    pub priority: u32,
    pub capabilities: Capabilities,
}

A backend known to the registry, plus the runtime facts needed to pick it.

available is supplied by the caller (typically the result of a cheap driver probe such as “did cuInit succeed?”). The registry never sets it itself, so this crate stays free of any device dependency.

Fields

kind: BackendKind

Which concrete backend this describes.

available: bool

Whether the backend is usable on this machine right now.

priority: u32

Selection priority — higher wins. Defaults to BackendKind::default_priority.

capabilities: Capabilities

What the backend can do (filled from a driver query, or a sensible default for the CPU/portable backends).

Implementations

impl BackendEntry

pub fn new(kind: BackendKind, available: bool) -> Self

Create an entry using the kind’s default priority and CPU-profile capabilities. Callers override capabilities after construction for real GPU backends.

pub fn with_priority(self, priority: u32) -> Self

Builder-style override of the priority.

pub fn with_capabilities(self, capabilities: Capabilities) -> Self

Builder-style override of the capability report.

Trait Implementations

impl Clone for BackendEntry

fn clone(&self) -> BackendEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendEntry

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

Formats the value using the given formatter.
