Struct devices::virtio::snd::common_backend::stream_info::StreamInfoBuilder

pub struct StreamInfoBuilder {
    stream_source_generator: Arc<Box<dyn StreamSourceGenerator>>,
    effects: Vec<StreamEffect>,
    card_index: usize,
}

StreamInfoBuilder builds a StreamInfo. It is used when we want to store the parameters to create a StreamInfo beforehand and actually create it later. (as is the case with VirtioSnd)

To create a new StreamInfoBuilder, see StreamInfo::builder().

Fields

stream_source_generator: Arc<Box<dyn StreamSourceGenerator>>

effects: Vec<StreamEffect>

card_index: usize

Implementations

impl StreamInfoBuilder

pub fn new( stream_source_generator: Arc<Box<dyn StreamSourceGenerator>>, card_index: usize, ) -> Self

Creates a StreamInfoBuilder with minimal required fields:

• stream_source_generator: Generator which generates stream source in StreamInfo::prepare().
• card_index: The ALSA card index.

pub fn effects(self, effects: Vec<StreamEffect>) -> Self

Set the StreamEffects to use when creating a stream from the stream source in StreamInfo::prepare(). The default value is no effects.

pub fn build(self) -> StreamInfo

Builds a StreamInfo.

Trait Implementations

impl Clone for StreamInfoBuilder

fn clone(&self) -> StreamInfoBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<StreamInfoBuilder> for StreamInfo

fn from(builder: StreamInfoBuilder) -> Self

Converts to this type from the input type.
