Enum FpdKey 

pub enum FpdKey {
    FPD,
    ServingTemp,
    HardnessAt14C,
}

Keys for accessing specific composition values from an FPD via FPD::get()

This exists largely to mirror how CompKey and Composition::get() work, which is helpful in downstream applications, e.g. to have a single flattened list of keys for properties; see PropKey and MixProperties::get().

Variants

FPD

Freezing Point Depression (FPD) in °C

This denotes the temperature at which a mix begins to freeze, which is typically depressed to a temperature lower than 0°C, that at which pure water freezes. This value is the first point on the frozen water curve at which the x-axis is 0% frozen water; see CurvePoint and Curves::frozen_water.

ServingTemp

Temperature at which the mix reaches a desired serving hardness

This is the y-value (temperature) intersection of the hardness FPD curve in Curves at a specific hardness value, typically 70-75% - defined by SERVING_TEMP_X_AXIS in current calculations.

HardnessAt14C

Hardness of the mix at -14°C, a typical target serving temperature for ice cream

This is the x-value (hardness) intersection of the hardness FPD curve at the specific y-value (temperature) of -14°C, a typical target serving temperature for ice cream.

Trait Implementations

impl Clone for FpdKey

fn clone(&self) -> FpdKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FpdKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FpdKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FpdKey> for PropKey

fn from(key: FpdKey) -> Self

Converts to this type from the input type.

impl Hash for FpdKey

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,

impl IntoEnumIterator for FpdKey

type Iterator = FpdKeyIter

fn iter() -> FpdKeyIter

impl KeyAsStrings for FpdKey

fn as_med_str(&self) -> &'static str

Returns a medium verbosity string representation of the key.

impl PartialEq for FpdKey

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

impl Serialize for FpdKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for FpdKey

impl Eq for FpdKey

impl StructuralPartialEq for FpdKey
