Pad state flags

Implementations

impl PadFlags[−]

pub const BLOCKED: PadFlags[−][−]

is dataflow on a pad blocked

pub const FLUSHING: PadFlags[−][−]

is pad flushing

pub const EOS: PadFlags[−][−]

is pad in EOS state

pub const BLOCKING: PadFlags[−][−]

is pad currently blocking on a buffer or event

pub const NEED_PARENT: PadFlags[−][−]

ensure that there is a parent object before calling into the pad callbacks.

pub const NEED_RECONFIGURE: PadFlags[−][−]

the pad should be reconfigured/renegotiated. The flag has to be unset manually after reconfiguration happened.

pub const PENDING_EVENTS: PadFlags[−][−]

the pad has pending events

pub const FIXED_CAPS: PadFlags[−][−]

the pad is using fixed caps. This means that once the caps are set on the pad, the default caps query function will only return those caps.

pub const PROXY_CAPS: PadFlags[−][−]

the default event and query handler will forward all events and queries to the internally linked pads instead of discarding them.

pub const PROXY_ALLOCATION: PadFlags[−][−]

the default query handler will forward allocation queries to the internally linked pads instead of discarding them.

pub const PROXY_SCHEDULING: PadFlags[−][−]

the default query handler will forward scheduling queries to the internally linked pads instead of discarding them.

pub const ACCEPT_INTERSECT: PadFlags[−][−]

the default accept-caps handler will check it the caps intersect the query-caps result instead of checking for a subset. This is interesting for parsers that can accept incompletely specified caps.

pub const ACCEPT_TEMPLATE: PadFlags[−][−]

the default accept-caps handler will use the template pad caps instead of query caps to compare with the accept caps. Use this in combination with PadFlags::AcceptIntersect. (Since: 1.6)

pub const fn empty() -> PadFlags[−]

Returns an empty set of flags

pub const fn all() -> PadFlags[−]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[−]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<PadFlags>[−]

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

pub const fn from_bits_truncate(bits: u32) -> PadFlags[−]

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> PadFlags[−]

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

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: PadFlags) -> bool[−]

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

pub const fn contains(&self, other: PadFlags) -> bool[−]

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

pub fn insert(&mut self, other: PadFlags)[−]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: PadFlags)[−]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: PadFlags)[−]

Toggles the specified flags in-place.

pub fn set(&mut self, other: PadFlags, value: bool)[−]

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