Enum Basis 

#[non_exhaustive]
pub enum Basis {
    Zero,
    Par,
}

The quote a sensitivity is expressed against.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Zero

The curve node’s own quote — a continuously compounded zero rate for a discount or projection curve, a hazard for a credit curve, and the parameter itself where it already is its quote.

This is the basis a risk pass produces directly, up to the per-family ∂p/∂q weight, and it needs nothing of the market beyond the curve families themselves.

Par

The calibrating instrument’s quote — the zero-basis gradient flipped through ∂z/∂q into one entry per rung of the ladder that built each curve.

Reportable only where every contributing curve was pinned with its ladder. A curve without one fails loud rather than dropping out of a ladder that would then silently describe part of the book.

Implementations

impl Basis

pub const ACCEPTED: &'static [&'static str]

Every spelling this vocabulary accepts, canonical forms first.

Matching additionally ignores case and _/-/whitespace — see normalize in core::vocabulary.

pub fn code(self) -> &'static str

The canonical code for this variant; round-trips through FromStr.

Trait Implementations

impl Clone for Basis

fn clone(&self) -> Basis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Basis

impl Debug for Basis

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

Formats the value using the given formatter.

impl Default for Basis

fn default() -> Basis

Returns the “default value” for a type.

impl Display for Basis

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

Formats the value using the given formatter.

impl Eq for Basis

impl FromStr for Basis

type Err = VocabularyParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Basis

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 Ord for Basis

fn cmp(&self, other: &Basis) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Basis

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

impl PartialOrd for Basis

fn partial_cmp(&self, other: &Basis) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
