Trait Implementations

impl Clone for FuncVolatility

fn clone(&self) -> FuncVolatility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FuncVolatility

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

impl<'de> Deserialize<'de> for FuncVolatility

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl PartialEq for FuncVolatility

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