Struct Add

pub struct Add;

Add two u64s.

Behavior

BEFORE: _ [right: u64] [left: u64]
AFTER:  _ [sum: u64]

Preconditions

• all input arguments are properly BFieldCodec encoded
• the sum of the arguments does not exceed u64::MAX

Postconditions

• the sum is the sum of the arguments
• the sum is properly BFieldCodec encoded

Implementations

Trait Implementations

impl BasicSnippet for Add

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

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

fn entrypoint(&self) -> String

fn code(&self, _: &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 Add

fn clone(&self) -> Add

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Add

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

Formats the value using the given formatter.

impl Hash for Add

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 Add

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