Struct BarycentricEvaluation

pub struct BarycentricEvaluation;

Use the barycentric Lagrange evaluation formula to extrapolate the codeword to an out-of-domain location. Codeword must have a length that is a power of 2 and may not exceed MAX_CODEWORD_LENGTH.

Trait Implementations

impl BasicSnippet for BarycentricEvaluation

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 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>

fn stack_diff(&self) -> isize

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

Contains an entry for every sign off.

impl Clone for BarycentricEvaluation

fn clone(&self) -> BarycentricEvaluation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BarycentricEvaluation

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

Formats the value using the given formatter.

impl Hash for BarycentricEvaluation

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 BarycentricEvaluation

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