Struct SystemBuilder 

pub struct SystemBuilder { /* private fields */ }

A builder for system definitions.

Examples

use async_flow::model::SystemBuilder;

let mut builder = SystemBuilder::new();
//let block = builder.register(MyBlock::new());
let system = builder.build();

Implementations

impl SystemBuilder

pub fn new() -> Self

Creates a new system builder.

pub fn register<T: BlockDefinition + 'static>(&mut self, block: T) -> Rc<T>

Registers an instantiated block with the system under construction.

pub fn register_port(&mut self, input: impl Into<PortId>)

Registers an input or output port with the system under construction.

pub fn register_input(&mut self, input: impl Into<InputPortId>)

Registers an input port with the system under construction.

pub fn register_output(&mut self, output: impl Into<OutputPortId>)

Registers an output port with the system under construction.

pub fn export( &mut self, input: impl Into<PortId>, ) -> Result<PortId, SystemBuildError>

Exports an input or output port registered with the system under construction.

pub fn export_port( &mut self, input: impl Into<PortId>, ) -> Result<PortId, SystemBuildError>

Exports an input or output port registered with the system under construction.

pub fn export_input( &mut self, input: impl Into<InputPortId>, ) -> Result<InputPortId, SystemBuildError>

Exports an input port registered with the system under construction.

pub fn export_output( &mut self, output: impl Into<OutputPortId>, ) -> Result<OutputPortId, SystemBuildError>

Exports an output port registered with the system under construction.

pub fn connect<T>( &mut self, output: &Outputs<T>, input: &Inputs<T>, ) -> Result<bool, SystemBuildError>

Connects an output port to an input port of the same type.

Returns a boolean indicating whether the connection was newly inserted or already existed.

pub fn build(self) -> SystemDefinition

Builds the system under construction.
