STRUCT

# allowlist

Represents a list of allowed values. Used by rules to represent allowed senders, recipients,
assets, and blockchain senders.

```signature
struct allowlist {
 allow_all: boolean = 0;
 allowed_values: list<byte_array>;
}
```

`allow_all: boolean = 0;`
:   whether all values are allowed. If true, the other field will be ignored

`allowed_values: list<byte_array>;`
:   list of allowed values. Empty means no values are allowed (except if `allow_all` is true)
