Struct qt_core::q_process::ProcessChannelMode

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

This enum describes the process output channel modes of QProcess. Pass one of these values to setProcessChannelMode() to set the current read channel mode.

C++ enum: QProcess::ProcessChannelMode.

C++ documentation:

This enum describes the process output channel modes of QProcess. Pass one of these values to setProcessChannelMode() to set the current read channel mode.

Note: Windows intentionally suppresses output from GUI-only applications to inherited consoles. This does not apply to output redirected to files or pipes. To forward the output of GUI-only applications on the console nonetheless, you must use SeparateChannels and do the forwarding yourself by reading the output and writing it to the appropriate output channels.

See also setProcessChannelMode().

Implementations

impl ProcessChannelMode

pub fn to_int(&self) -> c_int

impl ProcessChannelMode

pub const SeparateChannels: ProcessChannelMode = _

QProcess manages the output of the running process, keeping standard output and standard error data in separate internal buffers. You can select the QProcess’s current read channel by calling setReadChannel(). This is the default channel mode of QProcess. (C++ enum variant: SeparateChannels = 0)

pub const MergedChannels: ProcessChannelMode = _

QProcess merges the output of the running process into the standard output channel (stdout). The standard error channel (stderr) will not receive any data. The standard output and standard error data of the running process are interleaved. (C++ enum variant: MergedChannels = 1)

pub const ForwardedChannels: ProcessChannelMode = _

QProcess forwards the output of the running process onto the main process. Anything the child process writes to its standard output and standard error will be written to the standard output and standard error of the main process. (C++ enum variant: ForwardedChannels = 2)

pub const ForwardedOutputChannel: ProcessChannelMode = _

Complementary to ForwardedErrorChannel. (This value was introduced in Qt 5.2.) (C++ enum variant: ForwardedOutputChannel = 3)

pub const ForwardedErrorChannel: ProcessChannelMode = _

QProcess manages the standard output of the running process, but forwards its standard error onto the main process. This reflects the typical use of command line tools as filters, where the standard output is redirected to another process or a file, while standard error is printed to the console for diagnostic purposes. (This value was introduced in Qt 5.2.) (C++ enum variant: ForwardedErrorChannel = 4)

Trait Implementations

impl Clone for ProcessChannelMode

fn clone(&self) -> ProcessChannelMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessChannelMode

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

Formats the value using the given formatter.

impl From<ProcessChannelMode> for c_int

fn from(value: ProcessChannelMode) -> Self

Converts to this type from the input type.

impl From<i32> for ProcessChannelMode

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ProcessChannelMode

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