Struct DataResidency

pub struct DataResidency { /* private fields */ }

Where an operation’s inputs live and where its outputs are wanted.

Kept as a pair because they genuinely differ: a GPU broad phase may consume device-resident geometry and still have to deliver host-readable results.

Implementations

impl DataResidency

pub const HOST: Self

Both inputs and outputs in host memory. The portable default.

pub const fn new(input: Residency, output: Residency) -> Self

Construct an explicit input/output residency plan.

pub const fn input(self) -> Residency

Where inputs currently live.

pub const fn output(self) -> Residency

Where outputs are wanted.

pub fn is_transfer_free_on(self, backend: BackendId) -> bool

Whether running on backend needs no host/device transfer either way.

Trait Implementations

impl Clone for DataResidency

fn clone(&self) -> DataResidency

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataResidency

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

Formats the value using the given formatter.

impl Hash for DataResidency

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 DataResidency

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