Struct prob::Probability
[−]
[src]
pub struct Probability<T: Num>(pub T);
An independent probability.
This represents some probability of some abstract, isolated event occuring. Note that the even have to be isolated (independent of any other event) for the operations to be correct. As such, you shouldn't do calculations with conditional events. Stronger methods needs to be used for this.
This newtype simply wraps some numeral type and provides it with operations:
&for independent and.|for independent or.^for independent mutual exclusivity.!for inverse probability.
Methods
impl<T: Num + PartialOrd> Probability<T>[src]
fn certain() -> Probability<T>
The probability representing a "almost certain" condition.
"Almost certain" (a.c.) should not be equated with "certain", because something can be practically certain, but not impossible to fail. For example, pick a random natural number from an uniform distribution. Not picking a specific number would be almost certain, but it is not impossible, because an argument for impossibility could be applied to any number.
For practical purposes, though, there is no difference between certain and almost certain.
fn never() -> Probability<T>
The inverse of an "almost certain" condition (almost never).
fn half(self) -> Probability<T>
Half the probability.
fn fifty() -> Probability<T>
A fifty-fifty probability (0.5).
fn disjointed_or(self, rhs: Probability<T>) -> Probability<T>
'or' for mutually exclusive events
