Struct gstreamer_pbutils::element_properties::ElementPropertiesMapItem

pub struct ElementPropertiesMapItem(/* private fields */);

Wrapper around gst::Structure for element-properties-map map item.

Examples

ElementProperties::builder_map()
    .item(
        ElementPropertiesMapItem::builder("vp8enc")
            .field("max-quantizer", 17)
            .field("buffer-size", 20000)
            .field("threads", 16)
            .build(),
    )
    .build();

Trait Implementations

impl Clone for ElementPropertiesMapItem

fn clone(&self) -> ElementPropertiesMapItem

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElementPropertiesMapItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for ElementPropertiesMapItem

type Target = StructureRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for ElementPropertiesMapItem

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<ElementPropertiesMapItem> for Structure

fn from(e: ElementPropertiesMapItem) -> Self

Converts to this type from the input type.

impl PartialEq for ElementPropertiesMapItem

fn eq(&self, other: &ElementPropertiesMapItem) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
