Enum OptionKind 

pub enum OptionKind {
    Call,
    Put,
}

Which side of an option is held.

Variants

Call

The right to buy.

Put

The right to sell.

Implementations

impl OptionKind

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.

impl OptionKind

pub fn sign(self) -> f64

+1 for a call, −1 for a put — the sign that turns one formula into the other rather than duplicating it.

Trait Implementations

impl Clone for OptionKind

fn clone(&self) -> OptionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OptionKind

impl Debug for OptionKind

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

Formats the value using the given formatter.

impl Eq for OptionKind

impl FromStr for OptionKind

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 OptionKind

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