Struct xdpsock::UmemBuilder

pub struct UmemBuilder { /* fields omitted */ }

Initial step for building a UMEM. This creates the underlying mmap area.

Implementations

impl UmemBuilder

pub fn create_mmap(self) -> Result<UmemBuilderWithMmap>

Allocate a memory region for the UMEM.

Before we can create the UMEM we first need to allocate a chunk of memory, which will eventually be split up into frames. We do this with a call to mmap, requesting a read + write protected anonymous memory region.
