Struct MerkleRoot

pub struct MerkleRoot;

Compute the Merkle root of a slice of Digests. Corresponds to MerkleTree::sequential_new(leafs).root().

Behavior

BEFORE: _ *leafs
AFTER:  _ [root: Digest]

Preconditions

• *leafs points to a list of Digests
• the length of the pointed-to list is greater than 0
• the length of the pointed-to list is a power of 2
• the length of the pointed-to list is a u32

Postconditions

None.

Trait Implementations

impl BasicSnippet for MerkleRoot

fn inputs(&self) -> Vec<(DataType, String)>

fn outputs(&self) -> Vec<(DataType, String)>

fn entrypoint(&self) -> String

fn code(&self, library: &mut Library) -> Vec<LabelledInstruction>

fn sign_offs(&self) -> HashMap<Reviewer, SignOffFingerprint>

Contains an entry for every sign off.

fn annotated_code(&self, library: &mut Library) -> Vec<LabelledInstruction>

fn link_for_isolated_run(&self) -> Vec<LabelledInstruction>

fn init_stack_for_isolated_run(&self) -> Vec<BFieldElement>

Initial stack on program start, when the snippet runs in isolation.

fn stack_diff(&self) -> isize

impl Clone for MerkleRoot

fn clone(&self) -> MerkleRoot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleRoot

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

Formats the value using the given formatter.

impl Hash for MerkleRoot

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MerkleRoot

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