Struct MasteryWindow 

pub struct MasteryWindow {
    pub percentage: f32,
    pub range: (f32, f32),
}

A mastery window consists a range of scores and the percentage of the total exercises in the batch returned by the scheduler that will fall within that range.

Mastery windows are used by the scheduler to control the amount of exercises for a given range of difficulty given to the student to try to keep an optimal balance. For example, exercises that are already fully mastered should not be shown very often lest the student becomes bored. Very difficult exercises should not be shown too often either lest the student becomes frustrated.

Fields

percentage: f32

The percentage of the exercises in each batch returned by the scheduler whose scores should fall within this window.

range: (f32, f32)

The range of scores which fall on this window. Scores whose values are in the range [range.0, range.1) fall within this window. If range.1 is equal to 5.0 (the float representation of the maximum possible score), then the range becomes inclusive.

Implementations

impl MasteryWindow

pub fn in_window(&self, score: f32) -> bool

Returns whether the given score falls within this window.

Trait Implementations

impl Clone for MasteryWindow

fn clone(&self) -> MasteryWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MasteryWindow

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MasteryWindow

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MasteryWindow

fn eq(&self, other: &MasteryWindow) -> 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 MasteryWindow

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
