Enum DevicePickStrategy 

pub enum DevicePickStrategy {
    CostModel,
    Benchmark {
        runs: usize,
    },
}

How [GraphDevices::resolve_with_inputs] picks a backend when no hint is set.

Variants

Performs copy-assignment from source.

impl Copy for DevicePickStrategy

impl Debug for DevicePickStrategy

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

Formats the value using the given formatter.

impl Default for DevicePickStrategy

fn default() -> DevicePickStrategy

Returns the “default value” for a type.

impl Eq for DevicePickStrategy

impl PartialEq for DevicePickStrategy

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