Struct BufferDesc 

pub struct BufferDesc {
    pub size_bytes: usize,
    pub alignment: usize,
    pub pool_id: u32,
}

Descriptor for a pooled buffer slot.

Fields

size_bytes: usize

Size of the buffer in bytes.

alignment: usize

Required memory alignment in bytes.

pool_id: u32

Pool identifier this descriptor belongs to.

Implementations

impl BufferDesc

pub fn new(size_bytes: usize, alignment: usize, pool_id: u32) -> Self

Creates a new BufferDesc.

pub fn is_page_aligned(&self) -> bool

Returns true if the alignment equals 4096 (one memory page).

pub fn slots_needed(&self, slot_size: usize) -> usize

Returns how many slots of slot_size bytes are needed to hold this buffer.

Panics

Panics if slot_size is zero.

Trait Implementations

impl Clone for BufferDesc

fn clone(&self) -> BufferDesc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufferDesc

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

Formats the value using the given formatter.

impl PartialEq for BufferDesc

fn eq(&self, other: &BufferDesc) -> 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.
