Enum Backend 

pub enum Backend {
    Auto,
    Gpu,
    Cpu,
}

Which backend a caller wants for a scan. Auto places each call by what this process has measured at the input’s size: the CPU engine alone, or, for a pattern that reads only token kinds when a device is present, the input’s anchors split between the host’s cores and the device.

Variants

Auto

Choose per input (the default).

Gpu

Force the device; fall back to the CPU when the pattern is ineligible or no device is present.

Cpu

Force the CPU; never probe or touch the device.
