Struct gstreamer::PadLinkCheck[][src]

pub struct PadLinkCheck { /* fields omitted */ }

The amount of checking to be done when linking pads. [Self::Caps] and [Self::TemplateCaps] are mutually exclusive. If both are specified, expensive but safe [Self::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 ([Self::Default]) or the regular methods for linking the pads.

Implementations

impl PadLinkCheck[src]

pub const HIERARCHY: PadLinkCheck[src]

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[src]

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

pub const CAPS: PadLinkCheck[src]

Check if the pads are compatible by comparing the caps returned by crate::prelude::PadExt::query_caps().

pub const NO_RECONFIGURE: PadLinkCheck[src]

Disables pushing a reconfigure event when pads are linked.

pub const DEFAULT: PadLinkCheck[src]

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

pub const fn empty() -> PadLinkCheck[src]

Returns an empty set of flags

pub const fn all() -> PadLinkCheck[src]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<PadLinkCheck>[src]

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[src]

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

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

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

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: PadLinkCheck) -> bool[src]

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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