👑 Field Documentation 👑

🌈 struct rte_swx_match_field_params* fields

The set of match fields for the current table, bestie 🌸 and here's the restriction, don't ignore it (iykyk): all the match fields of the current table need to be part of the same struct — meaning either all the match fields are part of the same header, or all the match fields are part of the meta-data. no mixing, no matching your greens with your blues, pick a lane 💅

📌 Definition at line 659 of file rte_swx_pipeline.h.

⭐ uint32_t n_fields

The number of match fields for the current table. and okay so, if you set this to zero? literally no "regular" entries (i.e. entries other than the default entry) can be added to the current table, and the match process always results in a lookup miss 😭 like, it's giving empty vibes only. zero match fields = nothing to match = miss every time, periodt.

🦋 const char** action_names

The set of actions for the current table 🫶 that's it, that's the field, she's simple and she's iconic.

📌 Definition at line 669 of file rte_swx_pipeline.h.

🍓 int* action_is_for_table_entries

An array of n_actions flags, okay? for each action, the associated flag tells you whether that action can be assigned to regular table entries (when non-zero, i.e. true) or not (when zero, i.e. false) ✨ and when this is set to NULL, it just defaults to true for all the actions. generous queen behavior honestly 👑

🎀 int* action_is_for_default_entry

Another array of n_actions flags, same energy 🌸 for each action, the associated flag says whether the action can be assigned to the default table entry (non-zero, i.e. true) or not (zero, i.e. false). and again — when set to NULL, it defaults to true for all actions. she's consistent, we love her 💖

📌 Definition at line 683 of file rte_swx_pipeline.h.

🔥 uint32_t n_actions

The number of actions for the current table. Must be at least one. yes bestie, minimum one, this is not a zero-actions situation, that's the rule 🫶

📌 Definition at line 687 of file rte_swx_pipeline.h.

💀 const char* default_action_name

The default table action that gets executed on lookup miss 🙈 and it must be one of the table actions included in the action_names — like you can't just make one up, she has to already be on the list, no new girls allowed 💅

📌 Definition at line 692 of file rte_swx_pipeline.h.

🌸 const char* default_action_args

Default action arguments 💖 specified as a string with the format "ARG0_NAME ARG0_VALUE ...". and listen: the number of arguments in this string must match exactly the number of arguments of the default action. exactly. not one more, not one less, no cap 😭 and it must be NULL if the default action does not have any arguments. zero args = NULL, that's the assignment.

📌 Definition at line 699 of file rte_swx_pipeline.h.

🧚 int default_action_is_const

If non-zero (true), then the default action of the current table cannot be changed 🔒 locked in, frozen, no edits. If zero (false), then the default action can be changed in the future with another action from the action_names list — so basically the door's open, you just gotta pick from the list, iykyk 🦋

📌 Definition at line 706 of file rte_swx_pipeline.h.

🍓 const char* hash_func_name

Hash function name ⭐ when it's not set to NULL, it must point to one of the hash functions that were registered for the current pipeline. Ignored by the table implementation when not needed 🙈 and when it is needed but it's NULL? the table implementation will select the hash function to use — so she'll pick for you, no stress, main character energy 💅
