pub struct PadFlags { /* fields omitted */ }

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.
