Enum Backend 

pub enum Backend {
    GpuVello,
    CpuVello,
}

The chosen rasterizer.

Variants

GpuVello

The L0 SDF wgpu pipeline (and the vello L1 overlay) on a wgpu device — GPU rasterization, the fast path for large scenes. Wired behind the core wgpu feature; see [super::gpu].

CpuVello

vello_cpu — multithreaded SIMD software rasterization. Always available (it ships transitively inside epaint 0.34). The reference path here.

Implementations

impl Backend

pub fn is_gpu(self) -> bool

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

Human label for a status line / about box.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Backend

impl Debug for Backend

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

Formats the value using the given formatter.

impl Eq for Backend

impl PartialEq for Backend

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