Struct qt_gui::q_opengl_debug_logger::LoggingMode

pub struct LoggingMode(/* private fields */);

The LoggingMode enum defines the logging mode of the logger object.

C++ enum: QOpenGLDebugLogger::LoggingMode.

C++ documentation:

The LoggingMode enum defines the logging mode of the logger object.

Implementations

impl LoggingMode

pub fn to_int(&self) -> c_int

impl LoggingMode

pub const AsynchronousLogging: LoggingMode = _

Messages from the OpenGL server are logged asynchronously. This means that messages can be logged some time after the corresponding OpenGL actions that caused them, and even be received in an out-of-order fashion, depending on the OpenGL implementation. This mode has a very low performance penalty, as OpenGL implementations are heavily threaded and asynchronous by nature. (C++ enum variant: AsynchronousLogging = 0)

pub const SynchronousLogging: LoggingMode = _

Messages from the OpenGL server are logged synchronously and sequentially. This has a severe performance hit, as OpenGL implementations are very asynchronous by nature; but it’s very useful to debug OpenGL problems, as OpenGL guarantees that the messages generated by a OpenGL command will be logged before the corresponding command execution has returned. Therefore, you can install a breakpoint on the messageLogged() signal and see in the backtrace which OpenGL command caused it; the only caveat is that if you are using OpenGL from multiple threads you may need to force direct connection when connecting to the messageLogged() signal. (C++ enum variant: SynchronousLogging = 1)

Trait Implementations

impl Clone for LoggingMode

fn clone(&self) -> LoggingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LoggingMode

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

Formats the value using the given formatter.

impl From<LoggingMode> for c_int

fn from(value: LoggingMode) -> Self

Converts to this type from the input type.

impl From<i32> for LoggingMode

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for LoggingMode

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