DeadNodeEliminationPass

oximedia_graph::optimization

Struct DeadNodeEliminationPass

pub struct DeadNodeEliminationPass;

Expand description

Removes nodes whose outputs list is empty (i.e., no other node consumes their output).

Nodes with no outputs are considered dead unless they are the only node in the graph (treating them as implicit sinks).

Implementations§

impl DeadNodeEliminationPass

pub fn new() -> Self

Create a new dead-node elimination pass.

Trait Implementations§

impl Default for DeadNodeEliminationPass

fn default() -> Self

Returns the “default value” for a type. Read more

impl OptimizationPass for DeadNodeEliminationPass

fn name(&self) -> &str

Human-readable name of the pass.

fn optimize(&self, nodes: &mut Vec<NodeSpec>) -> usize
