Enum gfx::memory::Usage

#[repr(u8)]
pub enum Usage {
    Data,
    Dynamic,
    Upload,
    Download,
}

How this memory will be used regarding GPU-CPU data flow.

This information is used to create resources (see gfx::Factory).

Variants

Data

Full speed GPU access. Optimal for render targets and resourced memory.

Dynamic

CPU to GPU data flow with update commands. Used for dynamic buffer data, typically constant buffers.

Upload

CPU to GPU data flow with mapping. Used for staging for upload to GPU.

Download

GPU to CPU data flow with mapping. Used for staging for download from GPU.

Trait Implementations

impl Clone for Usage

fn clone(&self) -> Usage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for Usage

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

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].

impl PartialOrd<Usage> for Usage

fn partial_cmp(&self, other: &Usage) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Debug for Usage

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

Formats the value using the given formatter.

impl Ord for Usage

fn cmp(&self, other: &Usage) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl Eq for Usage

impl Copy for Usage

impl PartialEq<Usage> for Usage

fn eq(&self, other: &Usage) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
