LookupExpression type | Wartiva GraphQL API

Lookup represents an nftables expression for looking up a value in a set or map. This allows rules to efficiently check for membership or retrieve associated data.

Fields

Field Name	Description
`sourceRegister` - `NftRegister!`	The register holding the key value to look up in the set.
`destRegister` - `NftRegister!`	The register where the result of the lookup (e.g., associated data for maps) will be stored.
`isDestRegSet` - `Boolean!`	If true, the 'destRegister' field indicates that the lookup should populate this register with the result (e.g., the mapped value). If false, it's typically a membership check.
`setID` - `Uint32!`	The internal numeric ID of the target set or map.
`setName` - `String!`	The human-readable name of the target set or map.
`invert` - `Boolean!`	If true, the lookup result is inverted (e.g., matches if the key is not found).
