Enum BufferUsage 

pub enum BufferUsage {
    StaticDraw,
    DynamicDraw,
    StreamDraw,
    StreamRead,
    DynamicCopy,
}

Intended usage hint when creating a buffer.

Variants

StaticDraw

Data is set once and used many times (GL_STATIC_DRAW equivalent).

DynamicDraw

Data changes frequently and is used many times (GL_DYNAMIC_DRAW equivalent).

StreamDraw

Data changes every frame (GL_STREAM_DRAW equivalent).

StreamRead

GPU writes, CPU reads (GL_STREAM_READ equivalent).

DynamicCopy

GPU writes, GPU reads (GL_DYNAMIC_COPY equivalent).

Implementations

impl BufferUsage

pub fn to_gl(self) -> u32

Map to a GL enum value (integer form used by glow).

Trait Implementations

impl Clone for BufferUsage

fn clone(&self) -> BufferUsage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BufferUsage

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

Formats the value using the given formatter.

impl Hash for BufferUsage

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 BufferUsage

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