defmodule Explorer.Chain.MapCache do
@moduledoc """
Behaviour for a map-like cache of elements.
A macro based on `ConCache` is provided as well, at its minimum it can be used as;
```
use Explorer.Chain.MapCache,
name: :name,
keys: [:fst, :snd]
```
Note: `keys` can also be set singularly with the option `key`, e.g.:
```
use Explorer.Chain.MapCache,
name: :cache,
key: :fst,
key: :snd
```
Additionally all of the options accepted by `ConCache.start_link/1` can be
provided as well. By default only `ttl_check_interval:` is set (to `false`).
## Named functions
Apart from the functions defined in the behaviour, the macro will also create
3 named function for each key, for instance for the key `:fst`:
- `get_fst`
- `set_fst`
- `update_fst`
These all work as their respective counterparts with the `t:key/0` parameter.
## Callbacks
Apart from the `callback` that can be set as part of the `ConCache` options,
two callbacks esist and can be overridden:
`c:handle_update/3` will be called whenever an update is issued. It will receive
the `t:key/0` that is going to be updated, the current `t:value/0` that is
stored for said key and the new `t:value/0` to evaluate.
This allows to select what value to keep and do additional processing.
By default this just stores the new `t:value/0`.
`c:handle_fallback/1` will be called whenever a get is performed and there is no
stored value for the given `t:key/0` (or when the value is `nil`).
It can return 2 different tuples:
- `{:update, value}` that will cause the value to be returned and the `t:key/0`
to be `c:update/2`d
- `{:return, value}` that will cause the value to be returned but not stored
This allows to define of a default value or perform some actions.
By default it will simply `{:return, nil}`
