Struct MmapArea 

pub struct MmapArea<'a, T: Default + Copy> { /* private fields */ }

A mapped memory area used to move packets between the kernel and userspace. One or more Umem instances can share a Mmaparea.

Implementations

impl<'a, T: Default + Copy> MmapArea<'a, T>

pub fn new( buf_num: usize, buf_len: usize, options: MmapAreaOptions, ) -> Result<(Arc<MmapArea<'a, T>>, Vec<BufMmap<'a, T>>), MmapError>

Allocate a new memory mapped area based on the size and number of buffers

Arguments

• buf_num: The number of buffers to allocate in the memory mapped area
• buf_len: The length of each buffer
• options: Configuration options

pub fn get_ptr(&self) -> *mut c_void

Return the ptr to the memory mapped area.

pub fn get_buf_num(&self) -> usize

Get the number of buffers in the memory mapped area.

Trait Implementations

impl<'a, T: Debug + Default + Copy> Debug for MmapArea<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: Default + Copy> Drop for MmapArea<'a, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
