Enum glitter::buffer::BufferDataUsage

pub enum BufferDataUsage {
    StreamDraw,
    StaticDraw,
    DynamicDraw,
}

Provides a hint to the OpenGL driver for how a buffer will be used.

Variants

StreamDraw

Indicates that a buffer will be set once and drawn only a few times.

StaticDraw

Indicates that a buffer will be set once and drawn many times

DynamicDraw

Indicates that a buffer will be set and modified repeatedly and drawn many times.

Methods

impl BufferDataUsage

pub fn from_gl(gl_enum: GLenum) -> Result<Self, ()>

Convert from a raw OpenGL integer value to an enum variant. Returns an error if the value is not a valid enum variant.

pub fn gl_enum(&self) -> GLenum

Return the OpenGL integer value for a given enum variant.
