Struct Context

pub struct Context<O, D>
where
    O: Operation,
{
    pub graph: CompilationResult<O>,
    pub data: D,
}

A compilation context. This stores the current parse graph.

Fields

graph: CompilationResult<O>

The parse graph.

data: D

Data given by the consumer.

Implementations

impl<O, D> Context<O, D>

where O: Operation,

pub fn new(data: D) -> Self

Create a new Context.

pub fn add_node(&mut self, operation: O) -> NodeIndex

Add a node to the parse graph.

pub fn add_binary_operation( &mut self, operation: O, left: NodeIndex, right: NodeIndex, ) -> NodeIndex

Add a binary operation node to the parse graph and edges for the left and right operands.

pub fn add_unary_operation( &mut self, operation: O, parent: NodeIndex, ) -> NodeIndex

Add a unary operation node to the parse graph and an edge for the unary operand.

pub fn add_edge(&mut self, from: NodeIndex, to: NodeIndex, edge: EdgeInfo)

Add an edge between from and to.
