Struct NodeRef 

pub struct NodeRef<N: Node>(/* private fields */);

Reference to a VPP node

This is a per-node-instance structure containing metadata about the node and certain node state.

A &mut NodeRef corresponds to vlib_node_t * in C.

Implementations

impl<N: Node> NodeRef<N>

pub unsafe fn from_ptr_mut<'a>(ptr: *mut vlib_node_t) -> &'a mut Self

Creates a &mut NodeRef directly from a pointer

Safety

• The pointer must be valid and a properly initialised vlib_node_t.
• The pointer must stay valid and the contents must not be mutated for the duration of the lifetime of the returned object.
• The error_heap_index field must be set correctly to point to the base index of the node’s error counters in the VPP error main counters array.

pub fn as_ptr(&self) -> *mut vlib_node_t

Returns the raw pointer to the underlying vlib_node_t

pub fn increment_error_counter( &self, vm: &MainRef, counter: N::Errors, increment: u64, )

Increments the given error counter by the specified amount

This corresponds to the VPP C function vlib_node_increment_counter.
