Struct gstreamer::EventTypeFlags

pub struct EventTypeFlags { /* fields omitted */ }

EventTypeFlags indicate the aspects of the different EventType values. You can get the type flags of a EventType with the EventType::flags() function.

Implementations

impl EventTypeFlags

pub const STICKY_MULTI: EventTypeFlags

Multiple sticky events can be on a pad, each identified by the event name.

pub const fn empty() -> EventTypeFlags

Returns an empty set of flags

pub const fn all() -> EventTypeFlags

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

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

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

Removes the specified flags in-place.

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

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

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