ConstantFoldingPass

oximedia_graph::optimization

Struct ConstantFoldingPass

pub struct ConstantFoldingPass;

Expand description

Removes identity nodes whose output is always equal to their input.

Currently folds:

Scale nodes where the "factor" parameter is "1.0" or "1".

Implementations§

impl ConstantFoldingPass

pub fn new() -> Self

Create a new constant folding pass.

Trait Implementations§
