Enum SiftBackend 

pub enum SiftBackend {
    Cpu,
    WebGpu,
    WebGpuWithCpuFallback,
    WebGpuV2,
}

Backend selection for SIFT calculation.

Variants

Cpu

CPU only.

WebGpu

WebGPU only (errors are propagated up).

WebGpuWithCpuFallback

Try WebGPU first, silently fallback to CPU on error.

WebGpuV2

Full GPU V2 pipeline (texture-based, targeting <20ms).

Trait Implementations

impl Clone for SiftBackend

fn clone(&self) -> SiftBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SiftBackend

impl Debug for SiftBackend

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

Formats the value using the given formatter.

impl Default for SiftBackend

fn default() -> Self

Returns the “default value” for a type.

impl Eq for SiftBackend

impl FromStr for SiftBackend

type Err = String

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for SiftBackend

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