You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/tract/pulse/src/ops
    
    the code of the file until where you have to start completion: use std::any::Any;
use std::sync::RwLock;

use crate::internal::*;
use lazy_static::lazy_static;
use tract_pulse_opl::ops::Delay;

pub mod array;
pub mod cnn;
pub mod delay;
pub mod downsample;
pub mod dummy;
pub mod mask;
pub mod scan;
pub mod slice;
pub mod source;

pub(crate) fn sync_inputs(
    node: &TypedNode,
    target: &mut PulsedModel,
    mapping: &HashMap<OutletId, OutletId>,
) -> TractResu
    
    pub fn register<T: Any>(func: PulsifierFn) -> TractResult<()> {
        let inv = Self::inventory();
        let mut inv = inv.write().map_err(|e| anyhow!("Fail to lock inventory {e}"))?;
        inv.insert(
            std::any::TypeId::of::<T>(),
            OpPulsifier {
                type_id: std::any::TypeId::of::<T>(),
                name: std::any::type_name::<T>(),
                func,
            },
        );
        Ok(())
    }
