pub struct ApplicationFlags { /* private fields */ }

Expand description

Flags used to define the behaviour of a Application.

Implementations§

source §

impl ApplicationFlags

source

pub const FLAGS_NONE: Self = _

Default. Deprecated in 2.74, use G_APPLICATION_DEFAULT_FLAGS instead

source

pub const IS_SERVICE: Self = _

Run as a service. In this mode, registration fails if the service is already running, and the application will initially wait up to 10 seconds for an initial activation message to arrive.

source

pub const IS_LAUNCHER: Self = _

Don’t try to become the primary instance.

source

pub const HANDLES_OPEN: Self = _

This application handles opening files (in the primary instance). Note that this flag only affects the default implementation of local_command_line(), and has no effect if HANDLES_COMMAND_LINE is given. See ApplicationExtManual::run() for details.

source

pub const HANDLES_COMMAND_LINE: Self = _

This application handles command line arguments (in the primary instance). Note that this flag only affect the default implementation of local_command_line(). See ApplicationExtManual::run() for details.

source

pub const SEND_ENVIRONMENT: Self = _

Send the environment of the launching process to the primary instance. Set this flag if your application is expected to behave differently depending on certain environment variables. For instance, an editor might be expected to use the GIT_COMMITTER_NAME environment variable when editing a git commit message. The environment is available to the signal::Application::command-line signal handler, via ApplicationCommandLineExt::getenv().

source

pub const NON_UNIQUE: Self = _

Make no attempts to do any of the typical single-instance application negotiation, even if the application ID is given. The application neither attempts to become the owner of the application ID nor does it check if an existing owner already exists. Everything occurs in the local process. Since: 2.30.

source

pub const CAN_OVERRIDE_APP_ID: Self = _

Allow users to override the application ID from the command line with --gapplication-app-id. Since: 2.48

source

pub const ALLOW_REPLACEMENT: Self = _

Allow another instance to take over the bus name. Since: 2.60

source

pub const REPLACE: Self = _

Take over from another instance. This flag is usually set by passing --gapplication-replace on the commandline. Since: 2.60

source

pub const fn empty() -> Self

Returns an empty set of flags.

source

pub const fn all() -> Self

Returns the set containing all flags.

source

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

source

pub const fn from_bits(bits: u32) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

source

pub const fn from_bits_truncate(bits: u32) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

source

pub const unsafe fn from_bits_unchecked(bits: u32) -> Self

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

source

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

source

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

source

pub const fn intersects(&self, other: Self) -> bool

Returns true if there are flags common to both self and other.

source

pub const fn contains(&self, other: Self) -> bool

Returns true if all of the flags in other are contained within self.

source

pub fn insert(&mut self, other: Self)

Inserts the specified flags in-place.

source

pub fn remove(&mut self, other: Self)

Removes the specified flags in-place.

source

pub fn toggle(&mut self, other: Self)

Toggles the specified flags in-place.

source

pub fn set(&mut self, other: Self, value: bool)

Inserts or removes the specified flags depending on the passed value.

source

pub const fn intersection(self, other: Self) -> Self

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

source

pub const fn union(self, other: Self) -> Self

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

source

pub const fn difference(self, other: Self) -> Self

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

source

pub const fn symmetric_difference(self, other: Self) -> Self

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.
