# `Monty.Attention.Decay.NoopDecay`
[🔗](https://github.com/d-led/ex.tbp.monty/blob/v0.1.0/packages/ex_tbp_monty_core/lib/monty/attention/decay/noop_decay.ex#L1)

Decay that forgets nothing: Monty's `attention/decay.py::NoopDecay`.

Every weight survives every step, which is what a task wants when the thing
being looked for does not move and the sensor's attention should not fade.

# `t`

```elixir
@type t() :: %Monty.Attention.Decay.NoopDecay{}
```

# `decay`

Leave the grid as it is.

The decay itself is the first argument, as it is for every decay, and there is
nothing in it to read: this decay is the decision not to have one.
