C++ enum: QOpenGLBuffer::UsagePattern.

C++ documentation:

This enum defines the usage pattern of a QOpenGLBuffer object.

Implementations

impl UsagePattern

pub fn to_int(&self) -> c_int

impl UsagePattern

pub const StreamDraw: UsagePattern = _

The data will be set once and used a few times for drawing operations. Under OpenGL/ES 1.1 this is identical to StaticDraw. (C++ enum variant: StreamDraw = 35040)

pub const StreamRead: UsagePattern = _

The data will be set once and used a few times for reading data back from the OpenGL server. Not supported under OpenGL/ES. (C++ enum variant: StreamRead = 35041)

pub const StreamCopy: UsagePattern = _

The data will be set once and used a few times for reading data back from the OpenGL server for use in further drawing operations. Not supported under OpenGL/ES. (C++ enum variant: StreamCopy = 35042)

pub const StaticDraw: UsagePattern = _

The data will be set once and used many times for drawing operations. (C++ enum variant: StaticDraw = 35044)

pub const StaticRead: UsagePattern = _

The data will be set once and used many times for reading data back from the OpenGL server. Not supported under OpenGL/ES. (C++ enum variant: StaticRead = 35045)

pub const StaticCopy: UsagePattern = _

The data will be set once and used many times for reading data back from the OpenGL server for use in further drawing operations. Not supported under OpenGL/ES. (C++ enum variant: StaticCopy = 35046)

pub const DynamicDraw: UsagePattern = _

The data will be modified repeatedly and used many times for drawing operations. (C++ enum variant: DynamicDraw = 35048)

pub const DynamicRead: UsagePattern = _

The data will be modified repeatedly and used many times for reading data back from the OpenGL server. Not supported under OpenGL/ES. (C++ enum variant: DynamicRead = 35049)

pub const DynamicCopy: UsagePattern = _

The data will be modified repeatedly and used many times for reading data back from the OpenGL server for use in further drawing operations. Not supported under OpenGL/ES. (C++ enum variant: DynamicCopy = 35050)

Trait Implementations

impl Clone for UsagePattern

fn clone(&self) -> UsagePattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UsagePattern

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

Formats the value using the given formatter.

impl From<UsagePattern> for c_int

fn from(value: UsagePattern) -> Self

Converts to this type from the input type.

impl From<i32> for UsagePattern

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for UsagePattern

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
