Enum ScanBackend 

#[non_exhaustive]
pub enum ScanBackend {
    Gpu,
    SimdCpu,
    CpuFallback,
}

Scan execution backend selected for a given workload.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Gpu

GPU pattern matching via warpstate (for <100 patterns).

SimdCpu

Hyperscan NFA multi-pattern matching + SIMD prefilter. This is the primary high-throughput path on all platforms.

CpuFallback

Pure CPU: warpstate AC + regex. No Hyperscan, no GPU.

Implementations

impl ScanBackend

pub fn label(self) -> &'static str

Stable label for logs and CLI startup banner.

Trait Implementations

impl Clone for ScanBackend

fn clone(&self) -> ScanBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScanBackend

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

Formats the value using the given formatter.

impl PartialEq for ScanBackend

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