Enum dfir_lang::graph::GraphNode

pub enum GraphNode {
    Operator(Operator),
    Handoff {
        src_span: Span,
        dst_span: Span,
    },
    ModuleBoundary {
        input: bool,
        import_expr: Span,
    },
}

A node, corresponding to an operator or a handoff.

Variants

Operator(Operator)

An operator.

Handoff

A handoff point, used between subgraphs (or within a subgraph to break a cycle).

Fields

src_span: Span

The span of the input into the handoff.

dst_span: Span

The span of the output out of the handoff.

ModuleBoundary

Module Boundary, used for importing modules. Only exists prior to partitioning.

Fields

input: bool

If this module is an input or output boundary.

import_expr: Span

The span of the import!() expression that imported this module. The value of this span when the ModuleBoundary node is still inside the module is Span::call_site() TODO: This could one day reference into the module file itself?

Implementations

impl GraphNode

pub fn to_pretty_string(&self) -> Cow<'static, str>

Return the node as a human-readable string.

pub fn to_name_string(&self) -> Cow<'static, str>

Return the name of the node as a string, excluding parenthesis and op source code.

pub fn span(&self) -> Span

Return the source code span of the node (for operators) or input/otput spans for handoffs.
