Struct BufferHeader 

pub struct BufferHeader(pub *mut u8);

BufferHeader is the header of a buffer slice.

Layout: cap 4 byte | size 4 byte | start 4 byte | next 4 byte | flag 2 byte | unused 2 byte

Safety

Make sure it is well initialized before use and see ptr.offset method safety requirements.

Tuple Fields

0: *mut u8

Trait Implementations

impl Clone for BufferHeader

fn clone(&self) -> BufferHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BufferHeader

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

Formats the value using the given formatter.

impl PartialEq for BufferHeader

fn eq(&self, other: &BufferHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
