Generic traffic control action types.

These are the possible “outcomes” for a packet after an action is applied to it.

This enum is non-exhaustive as new action types may be added to the kernel at any time.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unspec

No specific outcome specified (i.e., take the default for that action).

Ok

Terminates packet processing and allows the packet to proceed.

Reclassify

Terminates packet processing and restart packet classification.

Shot

Drop the packet.

Pipe

Pipe the packet to the next action (if any).

Stolen

The packet is removed from this processing pipeline and returned to another. This happens, for example, when using the “mirred” redirect action.

Queued

Queue the packet for later processing.

Repeat

Repeat the action.

TODO: confirm this. I have not used this action before and its semantics are unclear.

Redirect

Redirect the packet.

TODO: confirm semantics of this action. It is unclear how Redirect differs from Stolen.

Trap

Transition packet processing from the hardware to software.

If this action is encountered by in software, it is equivalent to Shot.

Other(i32)

Other action types not known at the time of writing or not yet supported by this library.

Trait Implementations

impl Clone for TcActionType

fn clone(&self) -> TcActionType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TcActionType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TcActionType

fn default() -> TcActionType

Returns the “default value” for a type.

impl From<TcActionType> for i32

fn from(v: TcActionType) -> i32

Converts to this type from the input type.

impl From<i32> for TcActionType

fn from(d: i32) -> Self

Converts to this type from the input type.

impl PartialEq for TcActionType

fn eq(&self, other: &TcActionType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
