Struct FusionPlan 

pub struct FusionPlan {
    pub groups: Vec<FusionGroup>,
    pub node_to_group: HashMap<NodeId, usize>,
}

The complete fusion plan produced by the fusion pass.

Fields

groups: Vec<FusionGroup>

All fusion groups (including trivial single-node groups).

node_to_group: HashMap<NodeId, usize>

Map from NodeId to the FusionGroup index it belongs to.

Implementations

impl FusionPlan

pub fn fusion_count(&self) -> usize

Returns the number of non-trivial fusion groups (size ≥ 2).

pub fn nodes_saved(&self) -> usize

Returns the total number of nodes saved by fusion.

Each non-trivial group of size k saves k-1 kernel launches.

pub fn group_of(&self, node: NodeId) -> Option<&FusionGroup>

Returns the fusion group that owns node.

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

Performs copy-assignment from source.

impl Debug for FusionPlan

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