Struct libbpf_rs::TcHookBuilder

pub struct TcHookBuilder { /* private fields */ }

A TcHookBuilder is a way to ergonomically create multiple TcHooks All with similar initial values

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

Implementations

impl TcHookBuilder

pub fn new() -> Self

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

Set the initial file descriptor for created hooks this fd should come from a loaded libbpf_rs::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 Hook 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
