Struct ShiftLeft

pub struct ShiftLeft;

Shift left for unsigned 64-bit integers.

Behavior

BEFORE: _ [arg: u64] shift_amount
AFTER:  _ [result: u64]

Preconditions

• input argument arg is properly BFieldCodec encoded
• input argument shift_amount is in 0..64

Postconditions

• the output is the input argument arg bit-shifted to the left by input argument shift_amount
• the output is properly BFieldCodec encoded

Implementations

impl ShiftLeft

pub const SHIFT_AMOUNT_TOO_BIG_ERROR_ID: i128 = 370i128

Trait Implementations

impl BasicSnippet for ShiftLeft

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 ShiftLeft

fn clone(&self) -> ShiftLeft

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShiftLeft

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

Formats the value using the given formatter.

impl Hash for ShiftLeft

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 ShiftLeft

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