Struct qt_gui::q_opengl_buffer::RangeAccessFlag

#[repr(transparent)]
pub struct RangeAccessFlag(_);

This enum defines the access mode bits for QOpenGLBuffer::mapRange().

C++ enum: QOpenGLBuffer::RangeAccessFlag.

C++ documentation:

This enum defines the access mode bits for QOpenGLBuffer::mapRange().

The RangeAccessFlags type is a typedef for QFlags<RangeAccessFlag>. It stores an OR combination of RangeAccessFlag values.

Methods

impl RangeAccessFlag

pub fn to_int(&self) -> c_int

impl RangeAccessFlag

pub const RangeRead: RangeAccessFlag

The buffer will be mapped for reading. (C++ enum variant: RangeRead = 1)

pub const RangeWrite: RangeAccessFlag

The buffer will be mapped for writing. (C++ enum variant: RangeWrite = 2)

pub const RangeInvalidate: RangeAccessFlag

Discard the previous contents of the specified range. (C++ enum variant: RangeInvalidate = 4)

pub const RangeInvalidateBuffer: RangeAccessFlag

Discard the previous contents of the entire buffer. (C++ enum variant: RangeInvalidateBuffer = 8)

pub const RangeFlushExplicit: RangeAccessFlag

Indicates that modifications are to be flushed explicitly via glFlushMappedBufferRange. (C++ enum variant: RangeFlushExplicit = 16)

pub const RangeUnsynchronized: RangeAccessFlag

Indicates that pending operations should not be synchronized before returning from mapRange(). (C++ enum variant: RangeUnsynchronized = 32)
