Methods

pub unsafe fn from_glib_full(ptr: *const GstCaps) -> Self[src]

pub unsafe fn from_glib_borrow(ptr: *const GstCaps) -> Borrowed<Self>[src]

pub unsafe fn replace_ptr(&mut self, ptr: *mut GstCaps)[src]

pub fn make_mut(&mut self) -> &mut CapsRef[src]

pub fn get_mut(&mut self) -> Option<&mut CapsRef>[src]

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

pub unsafe fn into_ptr(self) -> *mut GstCaps[src]

impl Caps[src]

pub fn builder(name: &str) -> Builder<NoFeature>[src]

pub fn builder_full() -> BuilderFull<SomeFeatures>[src]

pub fn builder_full_with_features(
    features: CapsFeatures
) -> BuilderFull<SomeFeatures>
[src]

pub fn builder_full_with_any_features() -> BuilderFull<AnyFeatures>[src]

pub fn new_empty() -> Self[src]

Creates a new Caps that is empty. That is, the returned Caps contains no media formats. The Caps is guaranteed to be writable. Caller is responsible for unreffing the returned caps.

Returns

the new Caps

pub fn new_any() -> Self[src]

Creates a new Caps that indicates that it is compatible with any media format.

Returns

the new Caps

pub fn new_simple(name: &str, values: &[(&str, &dyn ToSendValue)]) -> Self[src]

Creates a new Caps that contains one Structure. The structure is defined by the arguments, which have the same format as Structure::new. Caller is responsible for unreffing the returned caps.

media_type

the media type of the structure

fieldname

first field to set

Returns

the new Caps

pub fn from_iter<'a, I>(iter: I) -> Self where
    I: IntoIterator<Item = &'a StructureRef>, 
[src]

pub fn from_iter_with_features<'a, 'b, I>(iter: I) -> Self where
    I: IntoIterator<Item = (&'a StructureRef, &'b CapsFeaturesRef)>, 
[src]

pub fn fixate(&mut self)[src]

Modifies the given self into a representation with only fixed values. First the caps will be truncated and then the first structure will be fixated with Structure::fixate.

This function takes ownership of self and will call gst_caps_make_writable on it so you must not use self afterwards unless you keep an additional reference to it with Caps::ref.

Note that it is not guaranteed that the returned caps have exactly one structure. If self are empty caps then then returned caps will be the empty too and contain no structure at all.

Calling this function with any caps is not allowed.

Returns

the fixated caps

pub fn merge(&mut self, other: Self)[src]

Appends the structures contained in caps2 to self if they are not yet expressed by self. The structures in caps2 are not copied -- they are transferred to a writable copy of self, and then caps2 is freed. If either caps is ANY, the resulting caps will be ANY.

caps2

the Caps to merge in

Returns

the merged caps.

pub fn merge_structure(&mut self, structure: Structure)[src]

Appends structure to self if its not already expressed by self.

structure

the Structure to merge

Returns

the merged caps.

pub fn merge_structure_full(
    &mut self,
    structure: Structure,
    features: Option<CapsFeatures>
)
[src]

Appends structure with features to self if its not already expressed by self.

structure

the Structure to merge

features

the CapsFeatures to merge

Returns

the merged caps.

pub fn normalize(&mut self)[src]

Returns a Caps that represents the same set of formats as self, but contains no lists. Each list is expanded into separate GstStructures.

This function takes ownership of self and will call gst_caps_make_writable on it so you must not use self afterwards unless you keep an additional reference to it with Caps::ref.

Returns

the normalized Caps

pub fn simplify(&mut self)[src]

Converts the given self into a representation that represents the same set of formats, but in a simpler form. Component structures that are identical are merged. Component structures that have values that can be merged are also merged.

This function takes ownership of self and will call gst_caps_make_writable on it if necessary, so you must not use self afterwards unless you keep an additional reference to it with Caps::ref.

This method does not preserve the original order of self.

Returns

The simplified caps.

pub fn truncate(&mut self)[src]

Discard all but the first structure from self. Useful when fixating.

This function takes ownership of self and will call gst_caps_make_writable on it if necessary, so you must not use self afterwards unless you keep an additional reference to it with Caps::ref.

Note that it is not guaranteed that the returned caps have exactly one structure. If self is any or empty caps then then returned caps will be the same and contain no structure at all.

Returns

truncated caps
