Struct libbpf_rs::OpenMap

pub struct OpenMap { /* private fields */ }

Represents a parsed but not yet loaded BPF map.

This object exposes operations that need to happen before the map is created.

Some methods require working with raw bytes. You may find libraries such as plain helpful.

Implementations

Trait Implementations

impl AsRawLibbpf for OpenMap

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