Struct libbpf_rs::Link[−][src]

pub struct Link { /* fields omitted */ }
Expand description

Represents an attached Program.

This struct is used to model ownership. The underlying program will be detached when this object is dropped if nothing else is holding a reference count.

Implementations

impl Link[src]

pub unsafe fn from_ptr(ptr: *mut bpf_link) -> Self[src]

Takes ownership from pointer.

Safety

It is not safe to manipulate ptr after this operation.

pub fn update_prog(&mut self, prog: Program) -> Result<()>[src]

Replace the underlying prog with prog.

pub fn pin<P: AsRef<Path>>(&mut self, path: P) -> Result<()>[src]

Pin this link to bpffs.

pub fn unpin(&mut self) -> Result<()>[src]

Unpin from bpffs

pub fn get_fd(&self) -> i32[src]

Returns the file descriptor of the link.
