Struct OpenObject

pub struct OpenObject { /* private fields */ }

Represents an opened (but not yet loaded) BPF object file.

Use this object to access OpenMaps and OpenPrograms.

Implementations

impl OpenObject

pub unsafe fn from_ptr(ptr: NonNull<bpf_object>) -> Self

Takes ownership from pointer.

Safety

Operations on the returned object are undefined if ptr is any one of: - null - points to an unopened bpf_object - points to a loaded bpf_object

It is not safe to manipulate ptr after this operation.

pub fn take_ptr(self) -> NonNull<bpf_object>

Takes underlying libbpf_sys::bpf_object pointer.

pub fn name(&self) -> Option<&OsStr>

Retrieve the object’s name.

pub fn maps(&self) -> impl Iterator<Item = OpenMap<'_>>

Retrieve an iterator over all BPF maps in the object.

pub fn maps_mut(&mut self) -> impl Iterator<Item = OpenMapMut<'_>>

Retrieve an iterator over all BPF maps in the object.

pub fn progs(&self) -> impl Iterator<Item = OpenProgram<'_>>

Retrieve an iterator over all BPF programs in the object.

pub fn progs_mut(&mut self) -> impl Iterator<Item = OpenProgramMut<'_>>

Retrieve an iterator over all BPF programs in the object.

pub fn load(self) -> Result<Object>

Load the maps and programs contained in this BPF object into the system.

Trait Implementations

impl AsRawLibbpf for OpenObject

fn as_libbpf_object(&self) -> NonNull<Self::LibbpfType>

Retrieve the underlying libbpf_sys::bpf_object.

type LibbpfType = bpf_object

The underlying libbpf type.

impl Debug for OpenObject

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

Formats the value using the given formatter.

impl Drop for OpenObject

fn drop(&mut self)

Executes the destructor for this type.
