Struct TcHookBuilder

pub struct TcHookBuilder<'fd> { /* private fields */ }

Builds TcHook instances.

TcHookBuilder is a way to ergonomically create multiple TcHooks, all with similar initial values.

Once a TcHook is created via the Self::hook() method, the TcHook’s values can still be adjusted before TcHook::attach() is called.

Implementations

impl<'fd> TcHookBuilder<'fd>

pub fn new(fd: BorrowedFd<'fd>) -> Self

Create a new TcHookBuilder with fd this fd should come from a loaded Program

pub fn ifindex(&mut self, ifindex: i32) -> &mut Self

Set the initial interface index to attach the hook on

pub fn parent(&mut self, maj: u32, min: u32) -> &mut Self

Set the initial parent of a hook

pub fn replace(&mut self, replace: bool) -> &mut Self

Set whether created hooks should replace existing hooks

pub fn handle(&mut self, handle: u32) -> &mut Self

Set the initial handle for a hook

pub fn priority(&mut self, priority: u32) -> &mut Self

Set the initial priority for a hook

pub fn hook(&self, attach_point: TcAttachPoint) -> TcHook

Create a TcHook given the values previously set

Once a hook is created, the values can still be changed on the TcHook by calling the TcHooks setter methods
