Enum YieldKernel 

#[non_exhaustive]
pub enum YieldKernel {
    Discounted(YieldBasis),
    Ise,
    JapaneseSimple,
}

The arithmetic a YieldQuoteMethod resolves to.

There are exactly three, and the count is the point. Most of what the market calls a distinct yield convention is the crate’s single price/yield body at a different YieldBasis; only two conventions are genuinely something else, and both are named here rather than hidden inside a fourth basis field.

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.

Discounted(YieldBasis)

The price/yield body at this basis. Serves periodic compounding and money-market simple interest, and is both arms of Self::Ise.

Ise

The ISE convention (calc 1014): Self::Discounted at the bond’s own basis before the final coupon period, and at simple interest over ACT/365 inside it — where exactly one flow remains, so the “closed form” the market quotes is the body with a single term.

Settlement decides which arm applies, so this cannot be one basis.

JapaneseSimple

The Japanese simple yield: (c·100 + (100 − clean)/n) / clean.

The one true outsider. It is linear in the clean price, discounts nothing, and inverts in closed form both ways — so it never reaches the body and never reaches a solver.

Trait Implementations

impl Clone for YieldKernel

fn clone(&self) -> YieldKernel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for YieldKernel

impl Debug for YieldKernel

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

Formats the value using the given formatter.

impl PartialEq for YieldKernel

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