Struct futuresdr::runtime::Topology

pub struct Topology { /* private fields */ }

The actual graph that backs a Flowgraph.

Implementations

impl Topology

pub fn new() -> Self

Constructs a blank Topology

pub fn block_id(&self, name: &str) -> Option<usize>

Get Id of a block, given its name

pub fn block_name(&self, id: usize) -> Option<&str>

Get name of a block, given its Id

pub fn add_block(&mut self, block: Block) -> usize

Adds a Block to the Topology returning the id of the Block in the Topology.

pub fn delete_block(&mut self, id: usize)

Removes a Block and all edges connected to the Block from the Topology.

pub fn connect_stream<B: BufferBuilder + Debug + Eq + Hash>( &mut self, src_block: usize, src_port: PortId, dst_block: usize, dst_port: PortId, buffer_builder: B ) -> Result<()>

Connect stream ports

pub fn connect_message( &mut self, src_block: usize, src_port: PortId, dst_block: usize, dst_port: PortId ) -> Result<()>

Connect message ports

pub fn validate(&self) -> Result<()>

Validate flowgraph topology

Make sure that all stream ports are connected. Check if connections are valid, e.g., every stream input has exactly one connection.

pub fn block_ref(&self, id: usize) -> Option<&Block>

Get reference to a block

pub fn block_mut(&mut self, id: usize) -> Option<&mut Block>

Get mutable reference to a block

Trait Implementations

impl Debug for Topology

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Topology

fn default() -> Self

Returns the “default value” for a type.
