Enum Direction 

pub enum Direction {
    Receive,
    Pay,
}

Whether a leg’s payments are received or paid.

Applied once, at the NPV fold, rather than per coupon — so an active mode records one negation for a leg instead of one for every cashflow in it.

Variants

Receive

Payments are received (+1). The default.

Pay

Payments are paid or financed (−1).

Implementations

impl Direction

pub fn sign(self) -> f64

The side’s sign.

pub fn flipped(self) -> Self

The other side. What a product turning a payer into a receiver applies to each of its legs, so the legs stay the trade’s rather than one orientation being remembered beside them.

impl Direction

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 Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl Eq for Direction

impl FromStr for Direction

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 PartialEq for Direction

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