Struct SignalFlags

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

The signal flags are used to specify a signal’s behaviour.

Implementations

impl SignalFlags

pub const RUN_FIRST: Self = _

Invoke the object method handler in the first emission stage.

pub const RUN_LAST: Self = _

Invoke the object method handler in the third emission stage.

pub const RUN_CLEANUP: Self = _

Invoke the object method handler in the last emission stage.

pub const NO_RECURSE: Self = _

Signals being emitted for an object while currently being in emission for this very object will not be emitted recursively, but instead cause the first emission to be restarted.

pub const DETAILED: Self = _

This signal supports “::detail” appendices to the signal name upon handler connections and emissions.

pub const ACTION: Self = _

Action signals are signals that may freely be emitted on alive objects from user code via g_signal_emit() and friends, without the need of being embedded into extra code that performs pre or post emission adjustments on the object. They can also be thought of as object methods which can be called generically by third-party code.

pub const NO_HOOKS: Self = _

No emissions hooks are supported for this signal.

pub const MUST_COLLECT: Self = _

Varargs signal emission will always collect the arguments, even if there are no signal handlers connected. Since 2.30.

pub const DEPRECATED: Self = _

The signal is deprecated and will be removed in a future version. A warning will be generated if it is connected while running with G_ENABLE_DIAGNOSTIC=1. Since 2.32.

pub const ACCUMULATOR_FIRST_RUN: Self = _

Only used in GSignalAccumulator accumulator functions for the GSignalInvocationHint::run_type field to mark the first call to the accumulator function for a signal emission. Since 2.68.

pub const fn empty() -> Self

Get a flags value with all bits unset.

pub const fn all() -> Self

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

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

Convert from a bits value.

This method will return None if any unknown bits are set.

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

Convert from a bits value, unsetting any unknown bits.

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

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

Whether all set bits in a source flags value are also set in a target flags value.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl SignalFlags

pub const fn iter(&self) -> Iter<SignalFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<SignalFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
