Struct BufferLayout 

pub struct BufferLayout { /* private fields */ }

Length and alignment of a buffer, with helpers for padding and validation.

Implementations

impl BufferLayout

pub fn new(len: usize, align: usize) -> Result<Self, EngineError>

Builds a layout, validating that align is a non-zero power of two.

pub const fn host(len: usize) -> Self

A host-aligned (HOST_ALIGN) layout.

pub const fn device(len: usize) -> Self

A device-aligned (DEVICE_ALIGN) layout.

pub const fn len(&self) -> usize

The requested length in bytes.

pub const fn is_empty(&self) -> bool

true when the buffer holds no bytes.

pub const fn align(&self) -> usize

The alignment in bytes.

pub const fn padded_len(&self) -> usize

The length rounded up to a multiple of the alignment (zero stays zero).

pub const fn is_aligned(&self, addr: usize) -> bool

true when addr satisfies this layout’s alignment.
