Struct libbpf_rs::Object [−][src]
pub struct Object { /* fields omitted */ }Expand description
Represents a loaded BPF object file.
An Object is logically in charge of all the contained Programs and Maps as well as
the associated metadata and runtime state that underpins the userspace portions of BPF program
execution. As a libbpf-rs user, you must keep the Object alive during the entire lifetime
of your interaction with anything inside the Object.
Note that this is an explanation of the motivation – Rust’s lifetime system should already be enforcing this invariant.
Implementations
impl Object[src]
impl Object[src]pub unsafe fn from_ptr(ptr: *mut bpf_object) -> Result<Self>[src]
pub unsafe fn from_ptr(ptr: *mut bpf_object) -> Result<Self>[src]Takes ownership from pointer.
Safety
If ptr is not already loaded then further operations on the returned object are
undefined.
It is not safe to manipulate ptr after this operation.
pub fn map<T: AsRef<str>>(&self, name: T) -> Option<&Map>[src]
pub fn map<T: AsRef<str>>(&self, name: T) -> Option<&Map>[src]Get a reference to Map with the name name, if one exists.
pub fn map_mut<T: AsRef<str>>(&mut self, name: T) -> Option<&mut Map>[src]
pub fn map_mut<T: AsRef<str>>(&mut self, name: T) -> Option<&mut Map>[src]Get a mutable reference to Map with the name name, if one exists.
pub fn maps_iter(&self) -> impl Iterator<Item = &Map>[src]
pub fn maps_iter(&self) -> impl Iterator<Item = &Map>[src]Get an iterator over references to all Maps.
Note that this will include automatically generated .data, .rodata, .bss, and
.kconfig maps. You may wish to filter this.
pub fn maps_iter_mut(&mut self) -> impl Iterator<Item = &mut Map>[src]
pub fn maps_iter_mut(&mut self) -> impl Iterator<Item = &mut Map>[src]Get an iterator over mutable references to all Maps.
Note that this will include automatically generated .data, .rodata, .bss, and
.kconfig maps. You may wish to filter this.
pub fn prog<T: AsRef<str>>(&self, name: T) -> Option<&Program>[src]
pub fn prog<T: AsRef<str>>(&self, name: T) -> Option<&Program>[src]Get a reference to Program with the name name, if one exists.
pub fn prog_mut<T: AsRef<str>>(&mut self, name: T) -> Option<&mut Program>[src]
pub fn prog_mut<T: AsRef<str>>(&mut self, name: T) -> Option<&mut Program>[src]Get a mutable reference to Program with the name name, if one exists.
pub fn progs_iter(&self) -> impl Iterator<Item = &Program>[src]
pub fn progs_iter(&self) -> impl Iterator<Item = &Program>[src]Get an iterator over references to all Programs.
pub fn progs_iter_mut(&mut self) -> impl Iterator<Item = &mut Program>[src]
pub fn progs_iter_mut(&mut self) -> impl Iterator<Item = &mut Program>[src]Get an iterator over mutable references to all Programs.
