Struct JoinNode 

pub struct JoinNode { /* private fields */ }

A Join node describe sequential execution. When the VM encounters a Join node, it executes the first child first and the second child second.

Implementations

impl JoinNode

Constants

pub const DOMAIN: Felt

The domain of the join block (used for control block hashing).

impl JoinNode

Public accessors

pub fn first(&self) -> MastNodeId

Returns the ID of the node that is to be executed first.

pub fn second(&self) -> MastNodeId

Returns the ID of the node that is to be executed after the execution of the program defined by the first node completes.

Trait Implementations

impl Clone for JoinNode

fn clone(&self) -> JoinNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinNode

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

Formats the value using the given formatter.

impl From<JoinNode> for MastNode

fn from(value: JoinNode) -> Self

Converts to this type from the input type.

impl MastNodeErrorContext for JoinNode

fn decorators<'a>( &'a self, forest: &'a MastForest, ) -> impl Iterator<Item = DecoratedOpLink> + 'a

The list of decorators tied to this node, along with their associated index.

fn get_assembly_op<'m>( &self, mast_forest: &'m MastForest, target_op_idx: Option<usize>, ) -> Option<&'m AssemblyOp>

Returns the AssemblyOp associated with this node and operation (if provided), if any.

impl MastNodeExt for JoinNode

fn digest(&self) -> Word

Returns a commitment to this Join node.

The commitment is computed as a hash of the first and second child node in the domain defined by Self::DOMAIN - i.e.,:

Hasher::merge_in_domain(&[first_child_digest, second_child_digest], JoinNode::DOMAIN);

fn before_enter<'a>(&'a self, forest: &'a MastForest) -> &'a [DecoratorId]

Returns the decorators to be executed before this node is executed.

fn after_exit<'a>(&'a self, forest: &'a MastForest) -> &'a [DecoratorId]

Returns the decorators to be executed after this node is executed.

type Builder = JoinNodeBuilder

Converts this node into its corresponding builder, reusing allocated data where possible.

fn to_display<'a>( &'a self, mast_forest: &'a MastForest, ) -> Box<dyn Display + 'a>

Returns a display formatter for this node.

fn to_pretty_print<'a>( &'a self, mast_forest: &'a MastForest, ) -> Box<dyn PrettyPrint + 'a>

Returns a pretty printer for this node.

fn has_children(&self) -> bool

Returns true if the this node has children.

fn append_children_to(&self, target: &mut Vec<MastNodeId>)

Appends the NodeIds of the children of this node, if any, to the vector.

fn for_each_child<F>(&self, f: F)

where F: FnMut(MastNodeId),

Executes the given closure for each child of this node.

fn domain(&self) -> Felt

Returns the domain of this node.

fn to_builder(self, forest: &MastForest) -> Self::Builder

fn verify_node_in_forest(&self, forest: &MastForest)

Verifies that this node is stored at the ID in its decorators field in the forest.

impl PartialEq for JoinNode

fn eq(&self, other: &JoinNode) -> 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.
