Enum Grade

pub enum Grade {
    INC,
    F,
    DMinus,
    D,
    DPlus,
    CMinus,
    C,
    CPlus,
    BMinus,
    B,
    BPlus,
    AMinus,
    A,
    APlus,
}

An equivalence class to categorize grades based on ranges of percentage point values. Derives PartialEq to reduce boilerplate. In Rust, the ordering of the discrimiants is important, such that the first listed discrimiant carries a value of 0, the next discrimiant a 1, and so on.

Implementations

impl Grade

pub fn eq_class(value: f32) -> Grade

Maps a score into its corresponding equivalence class

Trait Implementations

impl Debug for Grade

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

Formats the value using the given formatter.

impl Ord for Grade

fn cmp(&self, other: &Grade) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Grade

fn eq(&self, other: &Grade) -> 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 PartialOrd for Grade

fn partial_cmp(&self, other: &Grade) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
