Struct PlacedFragment 

pub struct PlacedFragment { /* private fields */ }

A graph node placed at a site with its wired input and output edges.

Identifies the fragment, holds the Expr node it evaluates, and tracks the StreamEdges feeding into and out of it.

Implementations

impl PlacedFragment

pub fn new(id: Symbol, node: Expr) -> Self

Creates a fragment for id evaluating node, with no edges yet.

pub fn with_input_edge(self, edge: StreamEdge) -> Self

Returns the fragment with edge appended to its input edges.

pub fn with_output_edge(self, edge: StreamEdge) -> Self

Returns the fragment with edge appended to its output edges.

pub fn id(&self) -> &Symbol

Returns the fragment identifier.

pub fn node(&self) -> &Expr

Returns the Expr node this fragment evaluates.

pub fn input_edges(&self) -> &[StreamEdge]

Returns the fragment’s input edges.

pub fn output_edges(&self) -> &[StreamEdge]

Returns the fragment’s output edges.

pub fn output_envelopes(&self) -> Vec<StreamEnvelope>

Collects the envelopes buffered across every output edge.

Trait Implementations

impl Clone for PlacedFragment

fn clone(&self) -> PlacedFragment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlacedFragment

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

Formats the value using the given formatter.

impl Eq for PlacedFragment

impl PartialEq for PlacedFragment

fn eq(&self, other: &PlacedFragment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
