Implementations

impl Block

pub async fn update(&mut self) -> Result<(), Error>

Update the Block, retrieving a new BlockDescription from the Flowgraph.

pub async fn call(&self, handler: Handler) -> Result<Pmt, Error>

Call a message handler of a Block, providing it a Pmt::Null.

This is usually used, when the caller is only interested in the return value. The handler might, for example, just return a parameter (think get_frequency, get_gain, etc).

pub async fn callback(&self, handler: Handler, pmt: Pmt) -> Result<Pmt, Error>

Call a message handler of a Block with the given Pmt.
