Struct CallNode 

pub struct CallNode { /* private fields */ }

A Call node describes a function call such that the callee is executed in a different execution context from the currently executing code.

A call node can be of two types:

• A simple call: the callee is executed in the new user context.
• A syscall: the callee is executed in the root context.

Implementations

impl CallNode

Constants

pub const CALL_DOMAIN: Felt

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

pub const SYSCALL_DOMAIN: Felt

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

impl CallNode

Public accessors

pub fn callee(&self) -> MastNodeId

Returns the ID of the node to be invoked by this call node.

pub fn is_syscall(&self) -> bool

Returns true if this call node represents a syscall.

pub fn domain(&self) -> Felt

Returns the domain of this call node.

Trait Implementations

impl Clone for CallNode

fn clone(&self) -> CallNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallNode

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

Formats the value using the given formatter.

impl From<CallNode> for MastNode

fn from(value: CallNode) -> Self

Converts to this type from the input type.

impl MastNodeErrorContext for CallNode

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 CallNode

fn digest(&self) -> Word

Returns a commitment to this Call node.

The commitment is computed as a hash of the callee and an empty word ([ZERO; 4]) in the domain defined by either Self::CALL_DOMAIN or Self::SYSCALL_DOMAIN, depending on whether the node represents a simple call or a syscall - i.e.,:

Hasher::merge_in_domain(&[callee_digest, Word::default()], CallNode::CALL_DOMAIN);

or

Hasher::merge_in_domain(&[callee_digest, Word::default()], CallNode::SYSCALL_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 = CallNodeBuilder

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 CallNode

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