indicates that `size` and `max_group_size` represent the maximum number of members that can be present across all selector groups and within a single selector group respectively.

indicates that `size` and `max_group_size` represent the maximum sum of weights that can be present across all selector groups and within a single selector group respectively.

used to list all possible actions in a Table.

Any metadata associated with controller Packet-IO (Packet-In or Packet-Out) is modeled as P4 headers carrying special annotations @controller_header("packet_out") and @controller_header("packet_in") respectively.

used to group all extern instances of the same type in one message.

Matches can be performed on arbitrarily-large inputs; the protobuf type 'bytes' is used to model arbitrarily-large values.

If the Optional match should be a wildcard, the FieldMatch must be omitted.

A Range is logically a set that contains all values numerically between 'low' and 'high' inclusively.

Empty message as no type information needed, just used as a placeholder in the oneof to identify boolean types.

Describes a P4_16 type.

For "safe" enums with no underlying representation and no member integer values.

Similar to an enum, but there is always one and only one instance per P4 program.

wrapping the enum in a message to avoid name collisions in C++, where "enum values are siblings of their type, not children of it".

New types introduced with the "type" keyword.

For serializable (or "unsafe") enums, which have an underlying type.

From the P4_16 spec: "A tuple is similar to a struct, in that it holds multiple values.

These P4 types (struct, header_type, header_union and enum) are guaranteed to have a fully-qualified name (e.g.

Top-level package documentation describing the forwarding pipeline config Can be used to manage multiple P4 packages.

Location of code relative to a given source file.

Corresponds to 'type' constructor parameter for Counter / DirectCounter in PSA.

Corresponds to 'type' constructor parameter for Meter / DirectMeter in PSA.

ids are allocated in such a way that it is possible based on an id to deduce the resource type (e.g.

this enum can be extended in the future with other behaviors, such as "HARD_EVICTION".
