pub struct LoopNode { /* private fields */ }Expand description
A Loop node defines condition-controlled iterative execution. When the VM encounters a Loop node, it will keep executing the body of the loop as long as the top of the stack is `1``.
The loop is exited when at the end of executing the loop body the top of the stack is 0``. If the top of the stack is neither 0nor1` when the condition is checked, the execution
fails.

Sourcepub fn new(
body: MastNodeId,
mast_forest: &MastForest,
) -> Result<LoopNode, MastForestError>
pub fn new( body: MastNodeId, mast_forest: &MastForest, ) -> Result<LoopNode, MastForestError>
Returns a new LoopNode instantiated with the specified body node.
Sourcepub fn new_unsafe(body: MastNodeId, digest: Word) -> LoopNode
pub fn new_unsafe(body: MastNodeId, digest: Word) -> LoopNode
Returns a new LoopNode from values that are assumed to be correct.
Should only be used when the source of the inputs is trusted (e.g. deserialization).
