Struct SourceNode 

pub struct SourceNode<OUTPUT: WriteChannelTrait + 'static> {
    pub id: String,
    pub write_channel: TypedWriteChannel<OUTPUT>,
    pub handler: Box<dyn SourceProcessor<OUTPUT = OUTPUT>>,
}

Source node structure. It is able to emit data without any input. The graph calls this node any time it’s not processing anything. Users must do their own frame rate control inside this method.

Fields

id: String

write_channel: TypedWriteChannel<OUTPUT>

handler: Box<dyn SourceProcessor<OUTPUT = OUTPUT>>

Implementations

impl<OUTPUT: WriteChannelTrait + 'static> SourceNode<OUTPUT>

pub fn create( id: String, processor: Box<dyn SourceProcessor<OUTPUT = OUTPUT>>, writer_channel: OUTPUT, ) -> SourceNode<OUTPUT>

Create a new SourceNode

• Arguments id - Id of the node. It must be unique in the graph. processor - A boxed instance of the processor that handles the data packets. write_channel - A WriteChannel object for output data.

pub fn create_common( id: String, processor: Box<dyn SourceProcessor<OUTPUT = OUTPUT>>, ) -> Self

A helper method for creating a SourceNode with the most common parameters instead of manually passing a ReadChannel.

• Arguments id - Id of the node. It must be unique in the graph. processor - A boxed instance of the processor that handles the data packets.
