Function create_validator 

pub fn create_validator(
    features: Features,
    downlevel: DownlevelFlags,
    flags: ValidationFlags,
) -> Validator

Available on crate feature unstable-wgpu-27 only.

Create a validator for Naga Modules.

Create a Naga Validator that ensures that each naga::Module presented to it is valid, and uses no features not included in features and downlevel.

The validator can only catch invalid modules and feature misuse reliably when the flags argument includes all the flags in ValidationFlags::default().
