Enum Alignment 

pub enum Alignment {
    Default,
    Align256,
    Align512,
    Align1024,
    Align4096,
    Custom(usize),
}

Specifies the byte alignment for a device memory allocation.

All variants represent alignments that are powers of two. The Custom variant is validated at allocation time.

Variants

Default

CUDA’s default allocation alignment (typically 256 bytes).

Align256

256-byte alignment.

Align512

512-byte alignment.

Align1024

1024-byte alignment.

Align4096

4096-byte (page) alignment.

Custom(usize)

User-specified alignment in bytes (must be a power of two).

Implementations

impl Alignment

pub fn bytes(&self) -> usize

Returns the alignment in bytes.

For Default, this returns 256 (the typical CUDA allocation alignment).

pub fn is_power_of_two(&self) -> bool

Returns true if the alignment value is a power of two.

This is always true for the named variants and may be false for Custom with an invalid value.

pub fn is_aligned(&self, ptr: u64) -> bool

Returns true if the given device pointer satisfies this alignment.

Trait Implementations

impl Clone for Alignment

fn clone(&self) -> Alignment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Alignment

impl Debug for Alignment

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

Formats the value using the given formatter.

impl Display for Alignment

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

Formats the value using the given formatter.

impl Eq for Alignment

impl Hash for Alignment

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Alignment

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