Struct FusionOptions 

pub struct FusionOptions {
    pub skip_fusion: bool,
    pub unfuse_elementwise_regions: bool,
    pub fusion_limits: FusionLimits,
}

Per-target fusion toggles (env-driven on Metal today).

Fields

skip_fusion: bool

Skip all pattern fusions (Metal: RLX_METAL_NO_FUSION).

unfuse_elementwise_regions: bool

Break ElementwiseRegion back into primitives after marking.

fusion_limits: FusionLimits

Caps for fused elementwise chains (encoder / scratch limits).

Implementations

impl FusionOptions

pub fn from_metal_env() -> FusionOptions

Read Metal-specific env overrides.

pub fn for_cpu() -> FusionOptions

CPU executes element-wise chains as per-op thunks — mark then unfuse.

Trait Implementations

impl Clone for FusionOptions

fn clone(&self) -> FusionOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionOptions

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

Formats the value using the given formatter.

impl Default for FusionOptions

fn default() -> FusionOptions

Returns the “default value” for a type.

impl PartialEq for FusionOptions

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