pub struct VideoCapsBuilder<T> { /* private fields */ }

Implementations

impl VideoCapsBuilder<NoFeature>

pub fn new() -> Self

Constructs an VideoCapsBuilder for the “video/x-raw” encoding.

If left unchanged, the resulting Caps will be initialized with:

• “video/x-raw” encoding.
• all available formats.
• maximum width range.
• maximum height range.

Use VideoCapsBuilder::for_encoding to specify another encoding.

pub fn for_encoding(encoding: impl IntoGStr) -> Self

Constructs an VideoCapsBuilder for the specified encoding.

The resulting Caps will use the encoding argument as name and will not contain any additional fields unless explicitly added.

pub fn field(self, name: impl IntoGStr, value: impl Into<Value> + Send) -> Self

Sets field name to the given value value.

Overrides any default or previously defined value for name.

pub fn field_if( self, name: impl IntoGStr, value: impl Into<Value> + Send, predicate: bool, ) -> Self

Sets field name to the given inner value if the predicate evaluates to true.

This has no effect if the predicate evaluates to false, i.e. default or previous value for name is kept.

pub fn field_if_some( self, name: impl IntoGStr, value: Option<impl Into<Value> + Send>, ) -> Self

Sets field name to the given inner value if value is Some.

This has no effect if the value is None, i.e. default or previous value for name is kept.

pub fn field_from_iter<V: ValueType + Into<Value> + FromIterator<SendValue> + Send>( self, name: impl IntoGStr, iter: impl IntoIterator<Item = impl ToSendValue>, ) -> Self

Sets field name using the given ValueType V built from iter’s the Items.

Overrides any default or previously defined value for name.

pub fn field_if_not_empty<V: ValueType + Into<Value> + FromIterator<SendValue> + Send>( self, name: impl IntoGStr, iter: impl IntoIterator<Item = impl ToSendValue>, ) -> Self

Sets field name using the given ValueType V built from iter’s Items, if iter` is not empty.

This has no effect if iter is empty, i.e. previous value for name is unchanged.
