Struct CompressionSupport 

pub struct CompressionSupport { /* private fields */ }

Describes whether and how a given device supports generic compression.

Construct via CompressionSupport::for_compute_capability to apply the capability gate (compression requires compute capability ≥ 8.0).

Implementations

impl CompressionSupport

pub fn for_compute_capability(major: u32, minor: u32) -> Self

Returns the compression support for a device with the given compute capability (major, minor).

Generic memory compression is an Ampere+ feature, so any capability with major >= 8 is considered supported. Older devices report unsupported with the granularity still set to the default (so that alignment math remains well-defined).

pub fn new(supported: bool, granularity: usize) -> Self

Builds an explicit support descriptor.

granularity is clamped to a minimum of 1 so that alignment never divides by zero.

pub fn is_supported(&self) -> bool

Returns true if generic compression is available.

pub fn granularity(&self) -> usize

Returns the allocation granularity in bytes.

Trait Implementations

impl Clone for CompressionSupport

fn clone(&self) -> CompressionSupport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompressionSupport

impl Debug for CompressionSupport

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

Formats the value using the given formatter.

impl Eq for CompressionSupport

impl PartialEq for CompressionSupport

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