Enum TvmVariable

pub enum TvmVariable {
    Rate,
    Periods,
    PresentValue,
    FutureValue,
}

Enumeration used for the calculated_field field in TvmSolution and [TvmSchedule] to keep track of what was calculated, either the periodic rate, the number of periods, the present value, or the future value.

Implementations

impl TvmVariable

pub fn is_rate(&self) -> bool

Returns true if the variant is TvmVariable::Rate indicating that the periodic rate was calculated from the number of periods, the present value, and the future value.

pub fn is_periods(&self) -> bool

Returns true if the variant is TvmVariable::Periods indicating that the number of periods was calculated from the periocic rate, the present value, and the future value.

pub fn is_present_value(&self) -> bool

Returns true if the variant is TvmVariable::PresentValue indicating that the present value was calculated from one or more periocic rates, the number of periods, and the future value.

pub fn is_future_value(&self) -> bool

Returns true if the variant is TvmVariable::FutureValue indicating that the future value was calculated from one or more periocic rates, the number of periods, and the present value.

Trait Implementations

impl Clone for TvmVariable

fn clone(&self) -> TvmVariable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TvmVariable

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

Formats the value using the given formatter.

impl Display for TvmVariable

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

Formats the value using the given formatter.

impl Hash for TvmVariable

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 PartialEq for TvmVariable

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