Struct gstreamer::PadLinkCheck

pub struct PadLinkCheck { /* fields omitted */ }

The amount of checking to be done when linking pads. PadLinkCheck::Caps and PadLinkCheck::TemplateCaps are mutually exclusive. If both are specified, expensive but safe PadLinkCheck::Caps are performed.

Only disable some of the checks if you are 100% certain you know the link will not fail because of hierarchy/caps compatibility failures. If uncertain, use the default checks (PadLinkCheck::Default) or the regular methods for linking the pads.

Implementations

impl PadLinkCheck

pub const HIERARCHY: PadLinkCheck

Check the pads have same parents/grandparents. Could be omitted if it is already known that the two elements that own the pads are in the same bin.

pub const TEMPLATE_CAPS: PadLinkCheck

Check if the pads are compatible by using their template caps. This is much faster than PadLinkCheck::Caps, but would be unsafe e.g. if one pad has GST_CAPS_ANY.

pub const CAPS: PadLinkCheck

Check if the pads are compatible by comparing the caps returned by PadExt::query_caps.

pub const NO_RECONFIGURE: PadLinkCheck

Disables pushing a reconfigure event when pads are linked.

pub const DEFAULT: PadLinkCheck

The default checks done when linking pads (i.e. the ones used by Pad::link).

pub const fn empty() -> PadLinkCheck

Returns an empty set of flags

pub const fn all() -> PadLinkCheck

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<PadLinkCheck>

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) -> PadLinkCheck

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

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

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: PadLinkCheck) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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